Andreas,

I ran into a warning about LDAPResult>>checkForExceptions sending the now deprecated #or:or:.  It was easy to silence (comment out the warning), but that won't fix the problem.

Maybe (untested):

checkForExceptions
     (  #( 0 5 6 ) includes:resultCode )
		ifFalse: [
			| ex |
			ex := LDAPException newWithCode: resultCode.
			ex signal: (errorMessage ifEmpty:[ex messageText]) ]
