RE: Optimizing OpenLDAP pam authentication (it's very slow)
Actually the "nss_base_passwd" and "nss_base_group" configuration options
tell pam_ldap and nss_ldap where to look for the appropriate objects. There
are other configuration options that you "AND" with the search filter, but
the "nss_base_*" options just tell the modules where to look to apply that
If you tell the modules where to look for the appropriate object, it should
speed up logins noticeably. If all of your objects lie in
ou=something,ou=people,dc=my,dc=com then use
in your /etc/ldap.conf file.
You're telling it EXACTLY where to look instead of doing a subtree search
I only wish there were a way to have multiple RFC2307bis naming contexts in
that file, because in my situation, users are all over the tree and if they
are in a container at the bottom of the tree alphabetically, then it takes
longer to do auth's and such. Active Directory doesn't support object
aliasing so I can't do that either :\
Oh well, try the nss_base_* config option; it should help speed things up.
Hope this helps.

I've seen that and tried that. What that does is "and" your filter
with the default filter. How to change/override the default filter would be
the trick. Right?
