Multi-server insallation, id zimbra user different

[wodel]

Hi,

I am testing a multi-server installation. with the following architecture.

1- A firewall acting as smtp-gateway for incoming and outgoing emails
2 - behind the firewall a load-balancer with haproxy for http(s), imap(s), pop3(s) and smtp(s) traffic.
3 - the load-balancer sends the traffic to two MTA-Proxy servers
4 - They use two Zimbra-ldap servers for authentication (a master and a slave)
5 - Emails are sent to two store servers (with webui).

I have noticed that on the the ldap servers the zimbra user has the uid=998 and gid=995 and it belongs to the tty group (gid 5)
On all other servers, the zimbra user has uid=997 the rest is the same except for MTA where the user also belongs to the postfix group.

Is this normal? could the different uid cause problems?

Zimbra does not choose a uid/gid, it uses the next available uid/gid on the system. Thus, for whatever reason, some of your systems must have an additional user than others do when you install zimbra, and so the next available uid/gid differs. Regardless, this doesn't matter. The uid/gid does not need to be the same across servers.
