It's just a name.

Post more details, like output of
getent passwd | grep joker

Open in new window

command.

Like I said, it's just a user name, there should be nothing special about it.  Run that getent command and see for yourself.

That's strange, but not worrying.  Can you run
id joker

Open in new window

instead?

It means that

user joker is having uid=1034 and it belongs to group SS_TS which gid is 10058, user joker also belongs to some other secondary groups "Domain Users, SS-Tipe, SS-LEA, SS-DS, SS-SW"

It seems that user joker is not in local system in "/etc/passwd" but you can check the other authendication database if configured, where user may available.

check the file :

cat /etc/nsswitch.conf

Check the below given value to identify which external source has been configured.


passwd:     files nis
shadow:     files nis
group:      files nis

files= your local system passwd file "/etc/passwd"
nis= NIS server is configured as central authentication database.

Judging by "Domain Users", it's either LDAP or Winbind...
