Hello, I'm upgrading one of our servers to the last HG 2.2.13 versión and I've found some problems with our configuration which has been working fine with previous versions.

We have a LDAP userdb for the users and a master userdb for user assistance, Until now the definition of usersdb in 10-auth.conf was:

!include auth-master.conf.ext !include auth-system.conf.ext !include auth-ldap.conf.ext

With the 2.2.12 version this worked fine but with 2.2.13+ version the LDAP users can't login in dovecot (IMAP), however the master users can login fine.

However, if I comment out the master userdb or change the order, i.e.

!include auth-system.conf.ext !include auth-ldap.conf.ext !include auth-master.conf.ext

In this case LDAP and master users can login normally.

Is this configuration change required for the new version or it's a bug?

Follows the log sections for both configurations

Regards Juan C. Blanco

There is the log for the first case (master before ldap) with debugging activated:
