dovecot - Apr 2007 - chdir failed, but requires group permissions

Using Debian Etch package dovecot-common and dovecot-pop3d, based on
1.0.rc15-2

 

My home directories are set up with 770 permissions as follows:

/home/<group name>/<user name>

 

Using this method, users MUST be a member of the appropriate group to
access their own home directory.  If they are not, they can't chdir past
/home.

 

This appears to kill dovecot with a "chdir failed with id xxxx:
Permission Denied" error, immediately after authenticating a pop3 user.

I was able to make a user the owner of the <group name> directory, and
dovecot succeeded

But when the <group name> directory is owned by <group
name>:<group
name> and the user is a member of the group - the process dies.

 

Any suggestions?

Could the group be the user's primary group? Then it works. Otherwise  
there's not much else you can do except modify the sources.

Thanks for the suggestion, 

That's a good idea, but unfortunately where the home directories lie, the
users actually need to be members of 2 groups - so they both can't be
primary.

However, it seems odd to me that Dovecot would REQUIRE access to the $HOME
directory, when I am only using it to pop mail from /var/mail (which it has full
access to) - and I am not using imap access at all.

Brent.
