Description of problem:

Splunk supports an LDAP configuration key like this:

groupBaseFilter = (|(cn=some-org-all)(cn=SplunkAdmin)(cn=some-ops)(cn=OurNOC))

This attribute cuts down on what's displayed on the role mapping screen on Splunk. RHQ seems to fail with this, but does support something similar to:

groupBaseFilter = |(cn=some-org-all)(cn=SplunkAdmin)(cn=some-ops)(cn=OurNOC)

Version-Release number of selected component (if applicable): 4.3

The LDAP test program shows something like:
**Verbose:debug ---- stack trace reference:javax.naming.directory.InvalidSearchFilterException: invalid attribute description; remaining name 'dc=xxx,dc=com'

The problem code:

modules/enterprise/server/jar/src/main/java/org/rhq/enterprise/server/resource/group/LdapGroupManagerBean.java

        if ((groupFilter != null) && (!groupFilter.trim().isEmpty())) {
            String filter = String.format("(%s)", groupFilter);
^^^
            return buildGroup(systemConfig, filter);
        }

() should not be added if there is () already.

Note: I also don't see anything logged in rhq-server-log4j.log when this fails. Is this something bizarre about the logging configuration? Mine is out-of-the-box.
