Ok - I've returned to my normal state of confusion. Prefetch
documentation says I need an explicit userdb for LDA/LMTP use.
Right.
And
somewhere I read I wasn't supposed to use the exact same filename
for
both userdb & passdb - but a symlink was good. What should I use
instead?
If you use the same filename, Dovecot uses the same LDAP connection
for
userdb and passdb lookups. Whether that's good or bad depends on the
situation. In your case it simply creates an extra LDAP connection
for
userdb lookups, which is never used.
Going back and reading the docs...again...
Auth-binds recommends the different connections for asynchronous
lookups to be faster - but since I'm using prefetch no userdb lookup is
ever performed, so it's a wasted connection...got it. Might want to add
a note to that effect in the auth-binds doc section, "This optimization
does not apply when using Prefetch for the userdb, as no lookup is
performed and having a separate LDAP connection defined for userdb use
is a waste."
