Re: ldap_search filter with memberOf

If you notice when you get the "memberOf" back from the server you ll see it is an array with full CN; so if you dont want to loop through the array returned you can try to see if filtering with the full CN will work. I found it easier to just get all of "memberOf" and then use PHP to get only the desired groups. On Feb 22, 2009, at 7:22 PM, Zaitchik, Alan wrote:

I am trying to construct a filter for ldap_search that tests the AD memberOf attribute. The latter has possibly multiple values for a given user, and I want something like (memberOf=*Student*) to get all and only the students. I realize that the above does not work, that the memberOf attribute has some internal structure that requires something more complicated, but I cannot seem to get it working. What I have done is use a very broad $filter, an $attribs that includes "memberOf"-- and then loop through the results keeping only the students, thus: $sr= ldap_search($ldapconn, $dn, $filter, $attribs); for ($entryid=ldap_first_entry($ldapconn,$sr);$entryid!=false;$entryid=ldap_next_entry($ldapconn,$entryid)){

                $this_memberof = implode(ldap_get_values($ldapconn,$entryid,'memberof'));

                If (stripos($this_memberof,'student') ) {

                                // do something, etc.

} } But this is wildly inefficient. How can I just create the filter I need for ldap_search? Thanks! Alan
