Hi all!
We are trying to implement a way to require an LDAP/OS user and password for a specific channel that the non MQ admins uses for MQ Explorer.
If we set the CONNAUTH's CHCKCLNT to 'required', it also affects the other channels (we do not want the applications to change the way they are currently connecting), and the 'optional' value would be as good as the 'none' in this case.
Is there any way to do it?
We currently have the CHLAUTH disabled, as we are using the blockip exit for the admin channel since our QMs were on v7 and below. |

You can upgrade a channel to require a password, where the queue manager wide setting is OPTIONAL, by using a CHLAUTH rule.
It would be possible to do this and also use the blockip2 exit, since the security exit always gets called to see if it would prefer to block the connection, even if CHLAUTH rules would have let it in.
You will have to ensure two things are set, before you go down this route though.
- CONNAUTH's CHCKCLNT(OPTIONAL) - NONE will not work
- CHLAUTH(ENABLED)
If you can go with these settings then you should be able to set a CHLAUTH rule something like:-
| Code: |
| SET CHLAUTH(channel-name) TYPE(ADDRESSMAP) ADDRESS('*') USERSRC(CHANNEL) CHCKCLNT(REQUIRED) |
Have a test in your environment and see how it sits together and let me know what you find.
Cheers,
Morag

For the values for Connauth for the queue manager I like to keep REQADM for checking client authorizations.
If a channel requires less, optional can be set at the qmgr level but you would then require a backstop rule to reinstate required for admins for everybody and make an exception at the channel level.
Hope this helps some.
