Consider the following before adding a user:
A user ID must be created before any permissions can be assigned to it.
The following internal CMS user IDs cannot be added as regular CMS users: inads, sroot, init, craft, con, nul, aux, com1 through com9, and lpt1 to lpt9.
If you add a user through an operating system utility, such as useradd, they must use the su command to assume the role of a valid CMS user. Users created through an operating system utility have the shell type /usr/bin/ksh. The User Data page in CMS Supervisor does not display users that were created using an operating system utility.
Users added through the User Data page will automatically have CMS launch when they log in. The shell for these users is /usr/bin/cms.
