[Dovecot] Random LDA failure to access auth socket

I'll give this a whirl tomorrow during off-mail time.  I'm thinking there
was a reason I did vmail:users, but it's not coming to me at the moment.

I'm also puzzled by why lda is using dovecot:dovecot rather than
vmail:users.  Does it drop back to dovecot:dovecot and retry if the
requested uid:gid fails to work?  I can't imagine where postfix would get
uid:gid of dovecot:dovecot to call with, so I don't think it's a postfix
problem.

Thanks for your help!
