ldap.config.mapper.attribute.user.filter using ldap not working correctly with commas.

Redback (i guess) security system replace in a wrong way the key user id in ldap.config.mapper.attribute.user.filter property.

Using ldap.config.mapper.attribute.user.filter=ismemberof=cn=apps.archiva,ou=group,dc=example,dc=com

Cases ldap query be like this:
(&(objectClass=<SOME_STRUCTURAL_OC>)(ismemberof=cn=apps.archiva(uid=admin))

The correct query, IMO, should be like this:
(&(objectClass=<SOME_STRUCTURAL_OC>)(ismemberof=cn=apps.archiva,ou=group,dc=example,dc=com)(uid=admin))',

as I specified before.

<SOME_STRUCTURA_OC> may be something like this: (objectClass=posixAccount), assembled using ldap.config.mapper.attribute.user.object.class property.

To solve (workarounding) the problem I had to hardcode all my ldap user mapping settings, in application.xml, like this:

<component>
<role>org.codehaus.plexus.redback.common.ldap.UserMapper</role>
<role-hint>ldap</role-hint>
<implementation>org.codehaus.plexus.redback.common.ldap.LdapUserMapper</implementation>
<configuration>
<email-attribute>email</email-attribute>
<full-name-attribute>cn</full-name-attribute>
<password-attribute>userPassword</password-attribute>
<user-id-attribute>uid</user-id-attribute>
<user-base-dn>ou=people,dc=ampliato,dc=com,dc=br</user-base-dn>
<user-object-class>posixAccount</user-object-class>
<user-filter>(ismemberof=cn=apps.archiva,ou=group,dc=ampliato,dc=com,dc=br)</user-filter>
</configuration>
<requirements>
<requirement>
<role>org.codehaus.plexus.redback.configuration.UserConfiguration</role>
</requirement>
</requirements>
</component>

Thats another related link around the same problem:

Solved, but It just doesn't fix the problem.
