Default user
The first user ID in the Users list is <Default User>.
To use
this function, your
user ID must have Modify permission for User Administration.
The Default User ID is used as the template
ID for users created with 
Create New
User. Edit this user ID if you want to change any of the default
settings. The initial defaults enable all the functions listed under
Cloud Pak System Software
Monitoring Portal Authorities except User Administration Create
and Modify. Any changes you make to the <Default User> ID apply
to users created from this point on; they do not affect any existing
user ID settings.
