[Dovecot] Problem with virtual mail user login users uid not permitted

[Neil Muller]

Hello,

I am trying to run exim 4.68 and dovecot 1.0.13 on Solaris 10 x86 5/08  
using dovecot lda and sieve with virtual users and domains, tls and  
ssl. At the moment certificates are from my internal CA Exim and  
Dovecot, dovecot lda and dovecot sieve were downloaded and installed  
from Blastwave. Mail delivery (ie from Exim to dovecot via dovecot  
lda) is working correctly but when I try to access mail using imap  
from a client (eg. Thunderbird) the login fails. My mail user for  
accessing virtual user mail is vmail (uid=954, gid=954). I have  
attached the messages from dovecot.log and the output of dovecot -n  
below as well as contents from the passdb file.

Can anyone point me to where I've gone wrong, I've had this working  
fine on Linux but Solaris just doesn't seem to want to play :-)

Thanks,

Neil
