Bug 55901

From Bugzilla Helper:
User-Agent: Mozilla/4.78 [en] (Windows NT 5.0; U)

Description of problem:
When attempting to parse a department search LDAP request from Outlook 2002, slapd gets confused and drops the connection.  Other 
Outlook 2002 searches are successful.  The equivalent request (e.g. department=com*) from the command-line ldapsearch tool parses 
correctly.  Naturally, since 'department' is not part of any standard schema, no results are returned.  The problem seems to be triggered by 
a combination of the attribute name not being in the server schema and the '84 xx xx xx xx' format that Outlook uses for the lengths.

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


How reproducible:
Always

Steps to Reproduce:
1. In Outlook 2002, attempt an LDAP search by department on an OpenLDAP 2.0.11-13 server.
2.
3.
	

Actual Results:  If the search string is at least 3 characters, Outlook complains 'LDAP directory not available'.

Expected Results:  'No entries found' at a minimum.
