Hi Jean-Paul, Thanks for this observation. You should issue a defect report. You should also issue one for the DOP problem. If you send it to SC6, please add DR numbers 346 and 347, as we get back in PDF from SC6.

The compatible definition should be: OsiRej ::= [4] IMPLICIT SEQUENCE { invokeId InvokeId, problem CHOICE { general [0] IMPLICIT GeneralProblem, invoke [1] IMPLICIT InvokeProblem, returnResult [2] IMPLICIT ReturnResultProblem, returnError [3] IMPLICIT ReturnErrorProblem }} Jean-Paul. ----- www.x500standard.com: The central source for information on the X.500 Directory Standard. ----- www.x500standard.com: The central source for information on the X.500 Directory Standard.
