Hi Oserome,
Why cant you try as follows,
• Create multiple masters (multi master replication)
• Use a load balancer ( hardware or software ie like linux virtual server)
for load balance between these multi master servers.
• Give a common fqdn in SAMBA which should resolve to load balancer and rest
will do the load balancer.
Thanks,
Premod

Subject: [Fedora-directory-users] Challenges with Fedora DS
Hi,
I currently use Fedora-DS integrated with Samba as my domain controller in an
organization with 141 offices. With only one domain controller I am able to
authenticate a user population of 5000 users, however as my organization grows I
have challenges daily with authentication. Every morning users trying to logon
to my Windows domain keep getting errors while siging on and this frequently
leads to account lockouts and frustation of users.
After going through your documentation on multiple load balanced FDS server
installation I still have all traffic coming to one server on the network. My
challenge is setting up FDS in the data centre on multiple servers to
authenticate my users while accommodating growth. Is there any suggestion you
can offer me or documentation where I can go through setup of a centalized FDS
cluster for a large user base?
I will greatly appreciate any help you can proffer.
Regards

Re: [Fedora-directory-users] Challenges with Fedora DS
Out of curiosity (I am still learning much about LDAP and DS), is a load balancer necessary or could it be done simply through round robin dns? For example, in our testing, we set up a replica ds. One is ldap01, the other is ldap02 and their certificates both have ldap as well as ldap01 or ldap01 in their subjAltNames. There are two entries in DNS for ldap - one pointing to ldap01 and the other to ldap02. Will such a setup work? For simply logging in, is a master necessary or can one use a read-only replica?

If clients directly hitting Directory server for auth, DNS round robin is sufficient, but if the hit to directory from a single host (say as in Oserome''s case SAMBA PDC), it will hit the next server only after the TTL value got expired. Otherwise it will hit o the same server only. And for logging purpose it doesn''t require Master, replica will be fine. ----- Original Message ----- From: "John A.
