Hi, I am trying to setup two redundant Samba Servers. The file shares are on both servers and needs to be synced. My best solution is to run an rsync between them every 5 min ? Are there any smarter solution to this? Another problem is how I could solve the kerberos authentication in the best possible way? We have a Windows AD server and authenticate through kerberos. If server1 is down I want to switch to server2 but use the same DNS / Computer name because all users have it mapped. It also saves the profiles. I have tried to set up a DNS alias on the AD server's DNS and my idea was that I just could switch the alias to the server I want to use. But that doesn't work because it is the alias name that tries to authenticate to kerberos and I then get: "Server not found in Kerberos database" on the kerberos server. I hope someone has a smart solution to this? / Linus

Hi Linus, I have been using heartbeat + DRBD for serveral years now, very reliable and excellent setup. I highly recommend it. If you are having issues with heartbeat V2 try version 1.XXX; I still use version 1. DRBD replicates the drives (raid1 over lan) very cool; heartbeat gives you a vurtual cluster IP. Time to do some reading ;) Adrian Sender From: Linus Hedström <linus@further.se> To: samba@lists.samba.org Subject: [Samba] Reduntant Samba servers?

Or are you using tdb backend for samba? Alan
Hi Linus
I use openldap with the slurpd to replicate the ldap database; this is the
propper way to replicate ldap to slave servers - there can only be one
master ldap server.
For further information about replicating openldap to slave ldap servers,
refer to samba 3 by example chapter 6 on the samba web site, it is pretty
easy to setup.
Cheers,
Adrian Sender
