Well I might have made a right royal mess of my Zimbra install.
Need to change the hostname as at the moment the EHLO does not match the external IP lookup. Some emails are getting black holed. Doh
Anyway using the zmlocalconfig -e command I changed all references to the new hostname. Ensured the new name resolved internally and restarted. First issues was with ldap not able to connect.
I then proceeded to try and edit the ldap server settings however can't seem to get my password accepted with Ldap Browser and using "uid=zimbra,cn=admins,cn=zimbra" for the username. Even attempted to issue a zmldappasswd command to reset the password.
Whats the best way forward. I think I need to logon to the ldap server to make some more config changes however can't logon using the ldap browser. Please help
