LDAP Authentication Troubleshooting Tips


The GroupWise POA will log each time it attempts to authenticate a user to the LDAP server. Make sure that the POA is on Verbose logging; Verbose logging shows you the POA user-authentication process. Figure 26.3 shows the user TKRATZER logging in, and the POA binding to the LDAP server at the IP address 137.65.55.211.

Figure 26.3. A POA log during LDAP authentication


The POA's log is going to be one of your best mechanisms for troubleshooting LDAP authentication. Some of the things to check include the following:

  • Does the POA seem to have LDAP authentication enabled? If not, rebuild the WPHOST.DB for the post office.

  • Is the server that is supposed to service LDAP requests running the NLDAP module?

  • Is the server that is supposed to service LDAP listening on port 389? Confirm this, with TCPCON on NetWare and netstat na on the Linux platform.

  • If the server is listening on port 389, are you sure it is eDirectory that is listening? If the server is also running the GroupWise GWIA, the GWIA may be listening on port 389. Or perhaps some other LDAP service is running.

  • Does the user you are authenticating as have an eDirectory account? Is the user's GroupWise object grafted to that eDirectory account?

  • Are there eDirectory problems that prevent the server running the NLDAP server from receiving information about the object? Perhaps using DSTRACE with LDAP filters will help to shake out this kind of a problem.

  • Perhaps you need to restart the LDAP services of eDirectory. For example:

    On NetWare:

    unload nldap nldap

    On Linux:

    /etc/rc.d/ndsd restart
