Section 10.3. Implementation
10.3. Implementation10.3.1. NetWare Migration Using LDAP BackendThe following software must be installed on the SUSE Linux Enterprise Server to perform this migration:
Each software application must be carefully configured in preparation for migration. The configuration files used at Abmas are provided as a guide and should be modified to meet needs at your site. 10.3.1.1 LDAP Server ConfigurationThe /etc/openldap/slapd.conf file Misty used is shown here: #/etc/openldap/slapd.conf # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/samba3.schema include /etc/openldap/schema/dhcp.schema include /etc/openldap/schema/misc.schema include /etc/openldap/schema/idpool.schema include /etc/openldap/schema/eduperson.schema include /etc/openldap/schema/commURI.schema include /etc/openldap/schema/local.schema include /etc/openldap/schema/courier.schema pidfile /var/run/slapd/run/slapd.pid argsfile /var/run/slapd/run/slapd.args replogfile /data/ldap/log/slapd.replog # Load dynamic backend modules: modulepath /usr/lib/openldap/modules ####################################################################### # Logging parameters ####################################################################### loglevel 256 ####################################################################### # SASL and TLS options ####################################################################### sasl-host ldap.corp.abmas.org sasl-realm DIGEST-MD5 sasl-secprops none TLSCipherSuite HIGH:MEDIUM:+SSLV2 TLSCertificateFile /etc/ssl/certs/private/abmas-cert.pem TLSCertificateKeyFile /etc/ssl/certs/private/abmas-key.pem password-hash {SSHA} defaultsearchbase "dc=abmas,dc=biz" ####################################################################### # bdb database definitions ####################################################################### database bdb suffix "dc=abmas,dc=biz" rootdn "cn=manager,dc=abmas,dc=biz" rootpw {SSHA}gdo/dUvoT4ZJmULz3rUt6A3H/hBEduJ5 directory /data/ldap mode 0600 # The following is for BDB to make it flush its data to disk every # 500 seconds or 5kb of data checkpoint 500 5 ## For running slapindex #readonly on ## Indexes for often-requested attributes index objectClass eq index cn eq,sub index sn eq,sub index uid eq,sub index uidNumber eq index gidNumber eq index sambaSID eq index sambaPrimaryGroupSID eq index sambaDomainName eq index default sub cachesize 2000 replica host=baa.corp.abmas.org:389 suffix="dc=abmas,dc=biz" binddn="cn=replica,dc=abmas,dc=biz" credentials=verysecret bindmethod=simple tls=yes replica host=ns.abmas.org:389 suffix="dc=abmas,dc=biz" binddn="cn=replica,dc=abmas,dc=biz" credentials=verysecret bindmethod=simple tls=yes ####################################################################### # ACL section ####################################################################### ## MOST RESTRICTIVE RULES MUST GO FIRST! # Admins get access to everything.

There are # possibilities to store hosts, services, ethers, and lots of other things. In my setup, users authenticate via PAM and NSS using LDAP-based accounts. The configuration file that controls the behavior of the PAM pam_unix2 module is shown in Example 10.3.2 file. This works out of the box with the configuration files in this chapter. It enables you to have no local accounts for users (it is highly advisable to have a local account for the root user). Traps for the unwary include the following:
I do have two LDAP slave servers configured. That subject is beyond the scope of this document, and steps for implementing it are well documented. The following services authenticate using LDAP:
Companywide white pages can be searched using an LDAP client such as the one in the Windows Address Book. Having gained a solid understanding of LDAP and a relatively workable LDAP tree thus far, it was time to configure Samba. I compiled the latest stable Samba and also installed the latest smbldap-tools from Idealx[1].
The Samba smb.conf file was configured as shown in Example 10.3.3. Most of these shares are only used by one company group, but they are required because of some ancient Qbasic and Rbase applications were that written expecting their own drive letters. Note: During the process of building the new server, I kept data files up to date with the Novell server via use of rsync. On a separate system (my workstation in fact), which could be rebooted whenever necessary, I set up a mount point to the Novell server via ncpmount. I then created a rsyncd.conf to share that mount point out to my new server, and synchronized once an hour. The script I used to synchronize is shown in Example 10.3.8. The files exclusion list I used is shown in Example 10.3.9. The reason I had to have the rsync daemon running on a system that could be rebooted frequently is because ncpfs (part of the MARS NetWare Emulation package) has a nasty habit of creating stale mount points that cannot be recovered without a reboot. The reason for hourly synchronization is because some part of the chain was very slow and performance-heavy (whether rsync itself, the network, or the Novell server, I am not sure, but it was probably the Novell server). Example 10.3.2. The PAM Control File /etc/security/pam_unix2.conf# pam_unix2 config file # # This file contains options for the pam_unix2.so module. # It contains a list of options for every type of management group, # which will be used for authentication, account management and # password management. Not all options will be used from all types of # management groups. # # At first, pam_unix2 will read this file and then uses the local # options. Not all options can be set her global. # # Allowed options are: # # debug (account, auth, password, session) # nullok (auth) # md5 (password / overwrites /etc/default/passwd) # bigcrypt (password / overwrites /etc/default/passwd) # blowfish (password / overwrites /etc/default/passwd) # crypt_rounds=XX # none (session) # trace (session) # call_modules=x,y,z (account, auth, password) # # Example: # auth: nullok # account: # password: nullok blowfish crypt_rounds=8 # session: none # auth: use_ldap account: use_ldap password: use_ldap session: none After Samba was configured, I initialized the LDAP database. The first thing I had to do was store the LDAP password in the Samba configuration by issuing the command (as root): root# smbpasswd -w verysecret where "verysecret" is replaced by the LDAP bind password. Example 10.3.3.

Example 10.3.5. Samba Configuration File smb.conf Part C
Now Samba was ready for use and it was time to configure the smbldap-tools. There are two relevant files, which are usually put into the directory /etc/smbldap-tools. The main file, smbldap.conf is shown in Example 10.3.10. Note: I chose not to take advantage of the TLS capability of this. Eventually I may go back and tweak it. Also, I chose not to take advantage of the master/slave configuration as I heard horror stories that it was unstable. My slave servers are replicas only. The /etc/smbldap-tools/smbldap_bind.conf file is shown here: # smbldap_bind.conf Example 10.3.6.

It creates a user called Administrator with UID=0 and GID=0 matching the Domain Admins group. This is fine because you can still log on as root to a Windows system, but it will break cached credentials if you need to log on as the administrator to a system that is not on the network. After the LDAP database has been preloaded, it is prudent to validate that the information needed is in the LDAP directory. This can be done done by restarting the LDAP server, then performing an LDAP search by executing: root# ldapsearch -W -x -b "dc=abmas,dc=biz"\ -D "cn=Manager,dc=abmas,dc=biz" \ "(Objectclass=*)" Enter LDAP Password: # extended LDIF # # LDAPv3 # base <dc=abmas,dc=biz> with scope sub # filter: (ObjectClass=*) # requesting: ALL # # abmas.biz dn: dc=abmas,dc=biz objectClass: dcObject objectClass: organization o: abmas dc: abmas # People, abmas.biz dn: ou=People,dc=abmas,dc=biz objectClass: organizationalUnit ou: People # Groups, abmas.biz dn: ou=Groups,dc=abmas,dc=biz objectClass: organizationalUnit ou: Groups # Idmap, abmas.biz dn: ou=Idmap,dc=abmas,dc=biz objectClass: organizationalUnit ou: Idmap ... Example 10.3.8.

This is also why I could only do one-way sync because # I could not fix the ACLs on the Novell side. find /data/samba/shares/Engr/ -perm +770 -exec chmod 770 {} \; find /data/samba/shares/Engr/! -group engr -exec chgrp engr {} \; else # This rsync took ages and ages -- I had it set to run every hour but # I needed a way to prevent it running into itself. echo "Oh no, rsync is already running!" echo "#############################################" fi Example 10.3.9. Rsync Files Exclusion List /root/excludes.txt/Acct/ /Apps/ /DATA/ /Engr/*.pc3 /Engr/plotter /Engr/APPOLO/ /Engr/LIBRARY/ /Home/Accounting/ /Home/Angie/ /Home/AngieY/ /Home/Brandon/ /Home/Carl/ With the LDAP directory now initialized, it was time to create the Windows and POSIX (UNIX) group accounts as well as the mappings from Windows groups to UNIX groups. The easiest way to do this was to use smbldap-groupadd command. It creates the group with the posixGroup and sambaGroupMapping attributes, a unique GID, and an automatically determined RID. I learned the hard way not to try to do this by hand. After I had my group mappings in place, I added users to the groups (the users don't really have to exist yet). I used the smbldap-groupmod command to accomplish this. It can also be done manually by adding memberUID attributes to the group entries in LDAP. The most monumental task of all was adding the sambaSamAccount information to each already existent posixAccount entry. I did it one at a time as I moved people onto the new server, by issuing the command: root# smbldap-usermod -a -P username I completed that step for every user after asking the person what his or her current NetWare password was. The wiser way to have done it would probably have been to dump the entire database to an LDIF file. This can be done by executing: root# slapcat > somefile.ldif Then update the LDIF file created by using a Perl script to parse and add the appropriate attributes and objectClasses to each entry, followed by re-importing the entire database into the LDAP directory. Rebuilding of the LDAP directory can be done as follows: root# rcldap stop root# cd /data/ldap root# rm *bdb _* log* root# su - ldap -c "slapadd -l somefile.ldif" root# rcldap start This can be done at any time and for any reason, with no harm to the database. I first added a test user, of course. The LDIF for this test user looks like this, to give you an idea: # Entry 1: cn=Test User,ou=people,ou=corp,dc=abmas,dc=biz dn:cn=Test User,ou=people,ou=corp,dc=abmas,dc=biz cn: Test User gecos: Test User gidNumber: 513 givenName: Test homeDirectory: /home/test.user homePhone: 555 l: Somewhere l: ST mail: test.user o: Corp objectClass: top objectClass: inetOrgPerson objectClass: posixAccount objectClass: sambaSamAccount postalCode: 12345 sn: User street: 10 Some St. uid: test.user uidNumber: 1074 sambaLogonTime: 0 sambaLogoffTime: 2147483647 sambaKickoffTime: 2147483647 sambaPwdCanChange: 0 displayName: Samba User sambaSID: S-1-5-21-725326080-1709766072-2910717368-3148 sambaLMPassword: 9D29C287C58448F9AAD3B435B51404EE sambaAcctFlags: [U] sambaNTPassword: D062088E99C95E37D7702287BB35E770 sambaPwdLastSet: 1102537694 sambaPwdMustChange: 1106425694 userPassword: {SSHA}UzFZ2VxRGdwUueLnTGtsTBtnsvMO1oj8 loginShell: /bin/false Then I went over to a spare Windows NT machine and joined it to the MEGANET2 domain. It worked, and the machine's account entry under ou=Computers looks like this: dn:uid=w2kengrspare$,ou=Computers,ou=MEGANET2,dc=abmas,dc=biz objectClass: top objectClass: inetOrgPerson objectClass: posixAccount objectClass: sambaSamAccount cn: w2kengrspare$ sn: w2kengrspare$ uid: w2kengrspare$ uidNumber: 1104 gidNumber: 515 homeDirectory: /dev/null loginShell: /bin/false description: Computer gecos: Computer sambaSID: S-1-5-21-725326080-1709766072-2910717368-3208 sambaPrimaryGroupSID: S-1-5-21-725326080-1709766072-2910717368-2031 displayName: W2KENGRSPARE$ sambaPwdCanChange: 1103149236 sambaPwdMustChange: 2147483647 sambaNTPassword: CA199C45CB6737035DB6D9D9F6CD1834 sambaPwdLastSet: 1103149236 sambaAcctFlags: [W ] So now I could log on with a test user from the machine w2kengrspare. It was all well and good, but that user was in no groups yet and so had pretty boring access. I fixed that by writing the login script! To write the login script, I used Kixtart[2] because it will work with every architecture of Windows, has an active and helpful user base, and was both easier to learn and more powerful than the standard netlogon scripts I have seen. I also did not have to do a logon script per user or per group.
I downloaded Kixtart and put the following files in my netlogon share: KIX32.EXE KX32.dll KX95.dll <-- Not needed unless you are running Win9x clients. kx16.dll <-- Probably not needed unless you are running DOS clients. kxrpc.exe <-- Probably useless as it has to run on the server and can only be run on NT. It's for Windows 95 to become group-aware. We can get around the need. I then wrote the logon.kix file that is shown in Example 10.3.14. I chose to keep it all in one file, but it can be split up and linked via include directives. As you can see in the script, I redirected the My Documents to the user's home share if he or she were not in the Laptop group. I also added printers on a group-by-group basis, and if applicable I set the group printer. For this to be effective, the print drivers must be installed on the Samba server in the [print$] share. Ample documentation exists about how to do that, so it is not covered here. I call this script via the logon.bat script in the [netlogon] directory: \\corpsrv\netlogon\kix32 \\corpsrv\netlogon\logon.kix /f I only had to fully qualify the paths for Windows 9x, as Windows NT and greater automatically add [NETLOGON] to the path. Also of note for Win9x is that the drive mappings and printer setup will not work because they rely on RPC. You merely have to put the appropriate settings into the c:\autoexec.bat file or map the drives manually. One option is to check the OS as part of the Kixtart script, and if it is Win9x and is the first login, copy a premade autoexec.bat to the C: drive. I have only three such machines, and one is going away in the very near future, so it was easier to do it by hand. At this point I was able to add the users. This is the part that really falls into upgrade. I moved the users over one group at a time, starting with the people who used the least amount of resources on the network. With each group that I moved, I first logged on as a standard user in that group and took careful note of the environment, mainly the printers he or she used, the PATH, and what network resources he or she had access to (most importantly, which ones the user actually needed access to). I then added the user's SambaSamAccount information as mentioned earlier, and join the computer to the domain. The very first thing I had to do was to copy the user's profile to the new server. This was very important, and I really struggled with the most effective way to do it. Here is the method that worked for every one of my users on Windows NT, 2000, and XP:
Words to the Wise:
After all these steps are accomplished, only cleanup details are left. Make sure user's shortcuts and Network Places point to the appropriate place on the new server, check the important applications to be sure they work as expected and troubleshoot any problems that might arise, and check to be sure the user's printers are present and working. By the way, if there are any network printers installed as system printers (the Novell way), you will need to log in as a local administrator and delete them. For my non-laptop systems, I would then log in and out a couple times as the user to be sure that his or her registry settings were modified, and then I was finished. Some compatibility issues that cropped up included the following: Blackberry client: It did not like having its registry settings moved around and so had to be reinstalled. Also, it needed write permissions to a portion of the hard drive, and I had to give it those manually on the one system where this was an issue. CAMedia: Digital camera software for Canon cameras caused all kinds of trouble with the registry. I had to use the Run as service to open the registry of the local user while logged in as the domain user, and give the domain user the appropriate permissions to some registry keys, then export that portion of the registry to a file. Then, as the domain user, I had to import that file into the registry. Crystal Reports version 7: More registry problems that were solved by recopying the user's profile. Printing from legacy applications: I found out that Novell sends its jobs to the printer in a raw format. CUPS sends them in PostScript by default. I had to make a second printer definition for one printer and tell CUPS specifically to send raw data to the printer, then assign this printer to the LPT port with Kixtart's version of the net use command. These were all eventually solved by elbow grease, queries to the Samba mailing list and others, and diligence. The complete migration took about 5 weeks. My userbase is relatively small but includes multiple versions of Windows, multiple Linux member servers, a mechanized saw, a pen plotter, and legacy applications written in Qbasic and R:Base, just to name a few. I actually ended up making some of these applications work better (or work again, as some of them had stopped functioning on the old server) because as part of the process I had to find out how things were supposed to work. The one thing I have not been able to get working is a very old database that we had around for reference purposes; it uses Novell's Btrieve engine. As the resources compare, I went from 95 percent disk usage to just around 10 percent. I went from a very high load on the server to an average load of between one and two runnable processes on the server. I have improved the security and robustness of the system. I have also implemented ClamAV[3] antivirus software, which scans the entire Samba server for viruses every 2 hours and quarantines them. I have found it much less problematic than our ancient version of Norton Antivirus Corporate Edition, and much more up-to-date.
In short, my users are much happier now that the new server is running, and that is what is important to me. Example 10.3.10.
