Hi friends,

could you please help me? I fumbled around for some time
now, looked at the imapd sources and searched the net but
could not solve the following problem:


When I call imapd for a user with a normal shell account
(e.g. the shell is /bin/bash for that user), imap-access
is doing fine. But when I use a dummy shell for the same
user (say /bin/false or similiar) imapd refuses to login
with the syslog-message

... imapd[27691]: Login failure user=blah host=blah ...

Any hint or idea? Anybody using imapd for users without shells?
Or are you doing it within chroot environments only?


I'm well aware, that the IMAP-protocoll gives the user some 
sort of shell on the system. But I would like to understand
how (and where) imapd is using the normal user's shell in 
addition to it's own system-access.

Thanks for your help
Michael

BTW the system is a SuSE 8.0 with imap-2000c-139
