            Bug ID: 55089
           Summary: Caching of LDAP credentials is not clearly documented
                    in mod_authnz_ldap
           Product: Apache httpd-2
           Version: 2.5-HEAD
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_authnz_ldap
          Assignee: [email protected]
          Reporter: [email protected]

When mod_authnz_ldap is used to restrict access to a resource, the LDAP
credentials are cached in mod_ldap.

The default setting of LDAPCacheTTL is 600. This allows a user to continue to
access a resource for 10 minutes after their credentials have been revoked.

Although this is documented for mod_ldap, it is not exposed in the default
httpd config file nor documented with mod_authnz_ldap. A naive administrator
may assume that revoking credentials takes effect immediately.

On a server where mod_authnz_ldap gives access to a user's profile, it could
allow a user whose account had been locked by an administrator to regain
access.

Suggestion: add a caveat to mod_authnz_ldap.html
