+.B pcacheTemplate <template_string> <attrset_index> <ttl> [<negttl> [<limitttl> [<ttr>]]]
+Specifies a cacheable template and "time to live" <ttl> of queries
+belonging to the template. An optional <negttl> can be used to specify
+that negative results (i.e., queries that returned zero entries)
+should also be cached for the specified amount of time. Negative
+results are not cached by default (<negttl> set to 0).
+An optional <limitttl> can be used to specify that results
+hitting a sizelimit should also be cached for the specified amount of time.
+Results hitting a sizelimit are not cached by default (<limitttl> set to 0).
+An optional <ttr> "time to refresh" can be used to specify that cached
+entries should be automatically refreshed after a certain time. Entries
+will only be refreshed while they have not expired, so the <ttl> should
+be larger than the <ttr> for this option to be useful. Entries are not
+refreshed by default (<ttr> set to 0).

+.TP
+.B pcacheBind <filter_template> <attrset_index> <ttr> <scope> <base>
+Specifies a template for caching Simple Bind credentials based on an
+already defined \fBpcacheTemplate\fP. The <filter_template> is similar
+to a <template_string> except that it may have some values present. Its
+purpose is to allow the overlay to generate filters similar to what other
+applications do when they do a Search immediately before a Bind. E.g.,
+if a client like nss_ldap is configured to search for a user with the
+filter "(&(objectClass=posixAccount)(uid=<username>))" then the corresponding
+template "(&(objectClass=posixAccount)(uid=))" should be used here. When
+converted to a regular template e.g. "(&(objectClass=)(uid=))" this
+template and the <attrset_index> must match an already defined
+\fBpcacheTemplate\fP clause. The "time to refresh" <ttr> determines the
+time interval after which the cached credentials may be refreshed. The
+first Bind request that occurs after that time will trigger the refresh
+attempt. Refreshes are not performed when the overlay is Offline. There
+is no "time to live" parameter for the Bind credentials; the credentials
+will expire according to the \fBpcacheTemplate\fP ttl. The <scope> and
+<base> should match the search scope and base used by the authentication
+clients. The cached credentials are not stored in cleartext, they are
+hashed using the default password hash.
+By default Bind caching is not enabled.
