+ for AuthLDAPBindPassword.
+ trunk patch: http://svn.apache.org/viewvc?view=revision&revision=1433478

PATCHES/ISSUES THAT ARE STALLED
* mod_cache: Realign the cache_quick_handler() to behave identically
module="mod_authnz_ldap">AuthLDAPBindDN</directive> and <directive
module="mod_authnz_ldap">AuthLDAPBindPassword</directive> if you
absolutely need them to search the directory.</p>
+
+ <p>If the value begins with exec: the resulting command will be
+ executed and the first line returned to standard output by the
+ program will be used as the password.</p>
+<example><pre>
+#Password used as-is
+AuthLDAPBindPassword secret
+
+#Run /path/to/program to get my password
+AuthLDAPBindPassword exec:/path/to/program
+
+#Run /path/to/otherProgram and provide arguments
+AuthLDAPBindPassword "exec:/path/to/otherProgram argument1"
+</pre></example>
+
</usage>
