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.

Subject: 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? Thanks - John

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
Osereme Osobase
