[plug] Strange LDAP issues

[Timothy White]

At the recent Workshop I managed to get LDAP partially working with
lots of help from kind people.
Unfortunately it's still doing something weird. As I'm not 100% sure
of what logging setting I should set slapd at to get useful
information I'm not going to try and debug slapd as I know it /should/
do recursive searches so I should have no problems.
I currently only have 1 user in LDAP (uid=dwhite,ou=People,dc=white,dc=lan)
$ldapsearch -x -D "uid=dwhite,ou=People,dc=white,dc=lan" -W
Enter LDAP Password:
....
Works fine.
But PAM/NSS and any other program using PAM auth fails to auth with
the ldap server. [1]

Any ideas would be welcomed.

Thanks

Tim
