I just tested this, and it works: pam_ldap follows referrals.

I had tcpdump running on the client and the debug logs running on both
the master and slave servers. The client was configured to query the
slave only.

Then I ran "passwd" and watched as it tried to run the update on the
slave, getting a referral, then updating the master. tcpdump got all the
updates, and showed it connecting to the right machines. I could clearly
see the referral URL and the passwords old and new.

So, I guess having a "host" entry that points to a RR DNS will be the
way I'll go on this one.

I'll just have to take care of the other scripts that insert/delete
users to ignore /etc/ldap.conf and point to the master directly.

Thanks a lot!
