<p>
The LDAP search filter used to find roles within the roleBase. The distinguished name of the user matched by
userSearchMatching is substituted into the {0} placeholder in the search filter. The client's username is
substituted into the {1} placeholder. For example, if you set this option to (member=uid={1})for the user
janedoe, the search filter becomes (member=uid=janedoe) after string substitution. It matches all role entries
that have a member attribute equal to uid=janedoe under the subtree selected by the roleBase.
