+ # 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.
