Hello,

I'm not sure if this is possible but need your advice to proceed on this.

Altered AUTHINFO('SYSTEM.DEFAULT.AUTHINFO.IDPWOS') to CHCKCLNT(OPTIONAL)

Now, when I set chlauth with CHCKCLNT(REQUIRED) so that channel is authenticated I get this error in the error logs.

Code:
AMQ5542: The failed authentication check was caused by the queue manager
CONNAUTH CHCKCLNT(OPTIONAL) configuration.


Is it not possible to authenticate channel connection without enabling at the qmgr level ?

If not possible, why does CHCKCLNT has options such as ASQMGR, OPTIONAL and REQUIRED ?

which means

At QMGR level if CHCKCLNT for IDPWOS is REQUIRED, then chlauth will be authenticated
At QMGR level if CHCKCLNT for IDPWOS is OPTIONAL, then chlauth is optional but can be set to REQUIRED ??
At QMGR level if CHCKCLNT for IDPWOS is any, then chlauth takes whatever the QMGR is set to from ASQMGR option.

Did you refresh security after the change?

figured out the issue. I was missing two changes.

1. update AUTHENMD to PAM for IDPWOS
2. set chlauth(MQADMIN.SVRCONN) TYPE(USERMAP) CLNTUSER('superhero') ADDRESS('*') MCAUSER('superhero') CHCKCLNT(REQUIRED) ACTION(REPLACE)

With these changes I was able to login using password.

One question though ? Is there a way to match USERMAP to group instead of id ?

You'd just have to use an id that's a member of the group...
