This hopefully works.
This seems to work fine and I had the idea of doing something similar for the userdb, but there it appears that the user name change doesn't happen.
auth_debug=yes userdb { driver = passwd-file args = username_format=%Lu /etc/dovecot/aliases result_success = continue-ok } userdb { driver = passwd-file args = username_format=%u /etc/passwd }
When I perform a lookup with doveadm user 'test@xinu.at' I get many
empty fields since the alias file doesn't have them set. I expected that
they would be fetched from the next userdb (/etc/passwd), but that
doesn't seem to happen. I get this in the log:
dovecot[10118]: auth: Debug: master in: USER 1 test@xinu.at service=doveadm debug dovecot[10118]: auth: Debug: passwd-file(test@xinu.at): lookup: user=test@xinu.at file=/etc/dovecot/aliases dovecot[10118]: auth: Debug: passwd-file(test@xinu.at): lookup: user=test@xinu.at file=/etc/passwd dovecot[10118]: auth: passwd-file(test@xinu.at): unknown user dovecot[10118]: auth: Debug: userdb out: USER 1 test@xinu.at
So it looks like the user name change doesn't get applied with userdb, while it works as expected with passdb. Is this expected or is this a bug?
Just for comparison, the passdb config is this:
passdb { driver = passwd-file args = username_format=%Lu /etc/dovecot/aliases } passdb { driver = pam }
And when logging in with doveadm auth test test@xinu.at the log looks like this:
dovecot[10118]: auth: Debug: auth client connected (pid=0) dovecot[10118]: auth: Debug: client in: AUTH 1 PLAIN service=doveadm debug resp=<hidden> dovecot[10118]: auth: Debug: passwd-file(test@xinu.at): lookup: user=test@xinu.at file=/etc/dovecot/aliases dovecot[10118]: auth: Debug: passwd-file(test@xinu.at): username changed test@xinu.at -> flo dovecot[10118]: auth: Debug: passwd-file(flo): Allowing any password dovecot[10118]: auth: Debug: passwd-file(flo): Not performing authentication (noauthenticate set) dovecot[10118]: auth-worker(10356): Debug: pam(flo): lookup service=dovecot dovecot[10118]: auth-worker(10356): Debug: pam(flo): #1/1 style=1 msg=Password: dovecot[10118]: auth: Debug: client passdb out: OK 1 user=flo original_user=test@xinu.at
