I found out the difference between Authenticating FC2 against a Win2k and Win2k3 domain. The latter denies access to read the directory to non-authenticated users. I can get passed it by either opening up 2k3 like 2k does or add a user just for this purpose and delegate that function to them and hard code that into the LDAP configuration file. I don't like those options. Question: Since Win2kX uses Kerberos to authenticate and LDAP for information, why can't I authenticate against Kerberos and use its ticket to get user information from LDAP? Anyone else seen this? I know Microsoft programmers leave a lot to be desired, but this is should be all on the client side. Use Kerberos authentication to grant access to read from LDAP. Did I miss something?
