Hi,
I installed MQ explorer v7 on my desktop with user id-sct.I was connecting to remote qmgrs on solaris server.I was able to connect to a qmgr A whose mcauser attribute of system.admin.svrconn channel is set to nobody.I browsed and got to know if mcauser is set to nobody,anyone can access to that queuemanager.Is that correct?And also,I connected to another qmgr Bwhose mcauser of svrconn channel is set to mqm.Now,I m having doubt how was I able to connect to qmgr B since my id is sct and not mqm.Can anyone please clear my doubts.I m a newbie and unable to find the reason how cld I connect to qmgr B frm user id- sct?
Thanks in advance |

MCAUSER always replaces whatever userid is sent by the other end of the channel.
If an MCAUSER is set to the value 'nobody', and this allows you to connect and have full access to the queue manager, it is because there exists a userid on the machine hosting the queue manager named 'nobody' and that userid has full mqm authorities to the queue manager. |

You did not understand the word 'replaces'. |

Also,as u said user nobody has full mqm authorities,I treid the below command on user nobody as below-It seems nobody doesnt have all access whereas mqm has.
Entity nobody has the following authorizations for object GCSXTA03:
inq
connect
dsp
setall
-bash-3.00$ dspmqaut -m GCSXTA03 -t qmgr -p mqm
Entity mqm has the following authorizations for object GCSXTA03:
inq
set
connect
altusr
crt
dlt
chg
dsp
setid
setall
system |

You are not sct user id, as far as the queue manager is concerned.
sct user id HAS BEEN REPLACED. |

Again you did not understand the word replaces. Specially for you:
The mcauserId (mqm) replaces ANY user set by the other end of the channel (sct)
