The subcommand imqusermgr delete deletes a user entry from the repository:
imqusermgr delete [-i brokerName] -u userName
The -u option specifies the user name of the entry to be deleted. If the broker name (-i option) is omitted, the default broker imqbroker is assumed.
For example, the following command deletes the user named AliBaba from the user repository on broker imqbroker:
imqusermgr delete -u AliBaba
