LDAP Version 2 Clients Receive Extended Characters Instead of IA5 for Search Queries

ID: Q196772

The information in this article applies to:

Microsoft Exchange Server, version 5.5

If Netscape Communicator version 4.5 is performing a Lightweight Directory Access Protocol (LDAP) search request against an Exchange Server computer for a directory entry containing extended characters, these characters are not displayed correctly.

CAUSE

Netscape Communicator 4.5 is a LDAP version 2 client and so expects to receive IA5 characters only.

RESOLUTION
