Authcachettl Option

The Messaging Server can cache the results of successful LDAP authentication (e.g., when logging into IMAP, POP or SMTP or when the MMP has preauth enabled). defines the length of time that authentication cache entries are preserved in seconds. Lower values will reduce performance, but result in faster recognition of server password changes. Higher values will increase performance, but result in delayed recognition of server password changes. Changes made to a  value in a user&#x27;s LDAP entry are not seen until the cache entry&#x27;s time-to-live (TTL) has expired. If you wish to have password changes seen at least every 15 minutes, then set the   value to 900.

The default value is: 900

Use with base
 The  base option specifies the length of time in seconds an authentication cache entry will remain valid. Set to 0 to disable authentication caching.

Note that setting   smaller than    causes the entire user entry to expire, thereby also expiring the user authentication information in the user entry.

The default value in this context is: 900

Use with the MMP
 The Messaging Server can cache the results of successful LDAP authentication (e.g., when logging into IMAP, or POP, or when the MMP has preauth enabled). The   option (available at base, MMP, IMAP Proxy, POP Proxy, and vdomain levels) defines the length of time that authentication cache entries are preserved in seconds. Lower values will reduce performance, but result in faster recognition of server password changes. Higher values will increase performance, but result in delayed recognition of server password changes. Changes made to a  value in a user&#x27;s LDAP entry are not seen until the cache entry&#x27;s time-to-live (TTL) has expired. If you wish to have password changes seen at least every 15 minutes, then set the   value to 900.
