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]) ] Bill
