GSSAPI mail home mapping problem

Hello,

I'm trying to map authenticated kerberos users to mail_location,

The problem when I set mail_home = /var/mail/virtual/domain1.zw.loca/%n works fine.

But if mail_home is set as /var/mail/virtual/%d/%n

I get

Apr 12 19:53:18 postfix10 dovecot: imap-login: Login: user=<user0>, method=GSSAPI, rip=172.16.0.44, lip=10.16.0.220, mpid=2428, session= Apr 12 19:53:18 postfix10 dovecot: imap(user0@domain1.zw.local =login_user=user0)<2428>: Debug: Added userdb setting: plugin/=yes Apr 12 19:53:18 postfix10 dovecot: imap(user0@domain1.zw.local =login_user=user0)<2428>: Debug: Effective uid=5000, gid=5000, home=/var/mail/virtual/domain1.zw.local =login_user=user0/user0

Right here, I can't figure out why login_user=user0/user0

Now login_user=user0

then login_user=user0/user0/mail
