It may be worth also having a look at this :
http://wikis.sun.com/display/SunJavaSystem/LDAP+Error+Codes

Error code 34 says "invalid DN syntax".

I am no LDAP specialist, but are you sure that the above "DOMAIN\username" is a valid way

of specifying the username ? It probably is so, in the Microsoft Active Directory version

of LDAP, but maybe they have replaced the server or changed its settings  ?

Note also that if this is part of an SSO system which obtains the user's Windows Domain 
userid, and then checks it with an AD or LDAP server : usually, you can obtain the user-id

in several forms, and the form "username@long.domain.name" may be more appropriate here.

Basically what I mean is that the error message above looks to me as if it is really an 
error returned by the LDAP server, and which the Java part is just reflecting.
That may be why you are not finding any code changes that may explain the issue.
