MQ does, in fact, support that, and I've used it. It's the "Channel Authentication" user mapping feature. I was just wondering if it was "directly supported" without a mapping, if the presented user ID was more than 8 characters. Thanks.

It is in theory possible for an application (such as MQ) to use z/OS security services to map an alternative identity (which might have different characteristics from a z/OS user ID) into a standard z/OS user ID. That can be done, for example, when applications support authentication via digital certificates, or via Kerberos (e.g., Windows Active Directory), or via LDAP. And there are additional mechanisms besides those three that z/OS supports. I have no idea whether MQ supports any of those alternative mechanisms, nor which ones, nor whether they're applicable in your environment. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
