Why are my LDAP filters not working?
OMERO users standard RFC 2254 LDAP filters (http://www.faqs.org/rfcs/rfc2254.html), so they must conform to that syntax and are only able to do what those filters can do. You can test the filters via ldapsearch on your OMERO server (assuming you have the OpenLDAP binaries installed).
Specific filters

LDAP server versions vary. Below, we link to various users experiences on their systems, which may be of use to you:
