Type: VT_I4
Typical R/W: R/W
Description: Impersonation Level
Indicates the level of impersonation that the server is allowed to use when impersonating the client. This property applies only to network connections other than Remote Procedure Call (RPC) connections; these impersonation levels are similar to those provided by RPC. One of the following:
- DB_IMP_LEVEL_ANONYMOUSThe client is anonymous to the server. The server process cannot obtain identification information about the client and cannot impersonate the client.
- DB_IMP_LEVEL_IDENTIFYThe server can obtain the client's identity. The server can impersonate the client for ACL checking but cannot access system objects as the client.
- DB_IMP_LEVEL_IMPERSONATEThe server process can impersonate the client's security context while acting on behalf of the client. This information is obtained when the connection is established, not on every call.
- DB_IMP_LEVEL_DELEGATEThe process can impersonate the client's security context while acting on behalf of the client. The server process can also make outgoing calls to other servers while acting on behalf of the client.
