dovecot - Apr 2016 - Different usernames for different login method

Hi again!

With Dovecot 2.2.9 authenticating against the Active Directory I have
following problem:

- if I login using LOGIN, PLAIN or CRAM, the username is REALM\login (in my
  case: CCH\lucabert)
- if I login using GSSAPI, the username is just login (in my case: lucabert)

this makes the access to the mailbox very difficult, since I don't what can
I
write in mail_location...
If I login with LOGIN, I can write:

	maildir:/home/mailboxes/%4.u/Maildir

but of course it does not work if I login using GSSAPI...

The mailboxes have just the login (in my case: lucabert).
Can someone explain me why %u is different and how can I solve my problem?

Thanks a lot

What does your passdb /userdb config looks like ?

You can return the "user" field, see 
http://wiki2.dovecot.org/PasswordDatabase , to mangle the username for 
all passdb's, in order to let Dovecot use the same username.

I solved the problem upgrading Dovecot to version 2.2.18 and using  
%{auth_username}...

Now I just have the problem, that mail_uid and mail_gid are ignored.
Any idea?
