ICH408I

Explanation
This error occurs when a user is logging on or
a batch job is being initiated, and RACF® detects
an unauthorized attempt to access a resource that has a security label
associated with it. It is issued when MLS WARN is specified, and means
that you failed a dominance check. For example, this message can be
issued if a user attempts to log on at a RACF-protected terminal,
and the profile protecting the terminal has a security label specified
for it.

System action
RACF allows
the request to complete.

User response
If the security label is misspelled, try again.
If you can log on (perhaps using a different security label), you
can find out which security labels you can use by entering the following RACF command:     SEARCH CLASS(SECLABEL)

To
find out which security label applies to the task you are currently
doing, see your installation security procedures or ask your RACF security administrator.
