Description of problem:

Using EAP 6.2.1 and Wndows AD 2008R2 as the LDAP server

- create an LDAP group that has a slash:
     CN=slash / group,CN=Users,DC=jbossuk,DC=com
- assign a user to that group
  the user can also be assigned to other groups.

- configure for RBAC:
            <security-realm name="ADManagementRealm">
                <authentication>
                    <ldap connection="adcon" base-dn="dc=jbossuk,dc=com" recursive="true">
                        <username-filter attribute="sAMAccountName"/>
                    </ldap>
                </authentication>
                <authorization>
                    <ldap connection="adcon">
                        <group-search group-dn-attribute="dn" group-name-attribute="cn">
                            <principal-to-group group-attribute="memberOf"/>
                        </group-search>
                    </ldap>
                </authorization>
            </security-realm>


    <management>
        <access-control provider="rbac">
            <role-mapping>
                <role name="SuperUser">
                    <include>
                        <user name="tom"/>
                        <user name="$local"/>
                        <group name="JBossAdmin"/>
                    </include>
                </role>
            </role-mapping>
        </access-control>
    </management>

Use the CLI, and login with that user:

Caused by: javax.security.sasl.SaslException: Authentication failed: all available authentication mechanisms failed


debugging lead to:

org.jboss.as.domain.management.security.LdapGroupSearcherService

        public LdapEntry[] groupSearch(DirContext dirContext, LdapEntry entry) throws IOException, NamingException {
            Set<LdapEntry> foundEntries = new HashSet<LdapEntry>();
            // Load the list of group.
            Attributes groups = dirContext.getAttributes(entry.getDistinguishedName(), new String[] {groupAttribute});
            Attribute groupRef = groups.get(groupAttribute);
            if (groupRef != null) {
                NamingEnumeration<String> groupRefValues = (NamingEnumeration<String>) groupRef.getAll();
                while (groupRefValues.hasMore()) {
                    String current = groupRefValues.next();
                    String groupName = null;
                    if (groupNameAttribute != null) {
                        // Load the Name
                        Attributes groupNameAttrs = dirContext.getAttributes(current, new String[] { groupNameAttribute });

The last line throws an exception:

e = (javax.naming.NamingException) javax.naming.NamingException: [LDAP: error code 1 - 000020D6: SvcErr: DSID-031007DB, problem 5012 (DIR_ERROR), data 0

(note: it would be nice if this was in fact send to the log file)

Remaining name contained two elements:
  CN=slash<space>
  <space>group,CN=Users,DC=jbossuk,DC=com

It seems the "/" is seen as a "syntaxSeparator" (this is a field on the object)
CN=slash
