- # Users can be temporarily disabled by adding a passdb with deny=yes.

- # Note that PAM can only be used to verify if user's password is correct,
- # so it can't be used as userdb. If you don't want to use a separate user
- # database (passwd usually), you can use static userdb.
-# passdb pam {

- #
- # cache_key can be used to enable authentication caching for PAM
- # (auth_cache_size also needs to be set). It isn't enabled by default
- # because PAM modules can do all kinds of checks besides checking password,
- # such as checking IP address. Dovecot can't know about these checks
- # without some help. cache_key is simply a list of variables (see
- # /usr/share/doc/dovecot-common/variables.txt) which must match for the
- # cached data to be used.
- # Here are some examples:
- # %u - Username must match. Probably sufficient for most uses.
- # %u%r - Username and remote IP address must match.
- # %u%s - Username and service (ie. IMAP, POP3) must match.
- #
- # If service name is "*", it means the authenticating service name
- # is used, eg. pop3 or imap.

- # args = session=yes *
- # args = cache_key=%u dovecot
