I have set up Virtualmin GPL with LDAP for both user accounts and for Postfix alias maps. User accounts are stored using @ format, and account creation seems to be working fine.
I have found one issue, however: if I set a forwarding address on a user account in Virtualmin, I receive the error:
Failed to save user : LDAP add of mailLocalAddress=mailtest\@domain.net,ou=Aliases,dc=domain,dc=net failed : invalid DN
It seems to not matter whether I create the user first and then add the forward, or if I create the user with a forward. I can create the user without a forward just fine, it’s not until the forward is added that the error appears.
After a lot of debugging, the problem appears to be with the ‘@’. Spamtrap and hamtrap aliases are being created, but they use a ‘-’ instead.
If I try to add the alias in Postfix manually, I receive the error " Failed to save alias : ‘mailtest@domain.net’ is not a valid address."
If I try to directly create the LDAP entry, I recieve the “invalid dn” error if I try to add “mailLocalAddress=mailtest\@domain.net,ou=Aliases,dc=domain,dc=net,” but I CAN add “mailLocalAddress=mailtest@domain.net,ou=Aliases,dc=domain,dc=net” without the escape.
So this is where I’m at. I would like users to log in with their regular email address, which is why I have “Format for usernames that include domain” set to “username@domain.” I’m not sure if this is what is causing a configuration conflict, or if there is a limitation in the Postfix module for LDAP aliases, if I’ve just missed something, or if I’ve stumbled on a bug.
As such, I’m not sure which configuration settings are relevant, so let me know what to provide. Thanks!
