Hello experts,
when we issue the setmqaut command, do we have to use -p or -g ?
IBM doc. says "Note: Although users on AIX and Linux can use the -p option for the dmpmqaut command, they must use -g groupname instead when defining authorizations."
But when I use -g , I get the error "AMQ7026E: A principal or group name was invalid."
But it works fine when I use "-p". |

When quoting official doc, please post the URL.

-oa group | user
[UNIX][Linux]On UNIX and Linux systems, you can specify whether group or user authorization is to be used. If you do not set this parameter, group authorization is used. You can change the authorization model later by setting the SecurityPolicy parameter in the Service stanza of the qm.ini file (see Service stanza format ). |
Is your security based on principal or group?

Is the string you supply with -g a group name or a user name? Your suggestion that it works fine when you use -p suggests it is a user name. It could of course be a group name as well but if it is not a group name then the error is exactly right.
Cheers,

It is both a user and group name, Morag.
I can see the output when i issue the command "id string" & "groups string". |

Is there anything interesting about the user and group repository that you are using? Is it just a basic on O/S repository, or are you using a PAM system, or some LDAP backed system? I guess what I'm getting at is, is there any way that the queue manager would not be able to correctly query a group name from the O/S because of, say, the level of authority the queue manager might have (not) been given to interact with the user/group repository.
I ask because the error message "AMQ7026E: A principal or group name was invalid." suggests the queue manager was unable to find the group name when it asked the O/S, but you are able to see it when you issue the groups command.
