OK, So it asks for base dn and root bind dn. i just used what was in iredmail.tips for explaining this simply. However I am not sure if root bind dn is Manager or vmailadmin.
So The First error is when I go to group creation, i receive this error:
Error adding new group.
ldap_add: No such object (32)
matched DN: o=domains,dc=domain,dc=com
So when I try to login as one of my ldap users, I recieve invalid username or password. And under the user's listing in the admin panel, there are no users listed.
It seems like it connecting to the ldap server, however I suppose it is not. All the log errors seem to indicate that.
