===== Limit Users =====
* Edit the lsb.users file in /etc/cfm/template/lsf/lsbatch/default/configdir/
* The following example sets up the user david with MAX_JOBS=5 and everyone in the ugrads group=5

<syntaxhighlight>
Begin UserGroup
GROUP_NAME GROUP_MEMBER USER_SHARES #GROUP_ADMIN
#ugroup1 (user1 user2 user3 user4) ([user1, 4] [others, 10]) #()
#ugroup2 (all) ([user3, 10] [others, 15]) #()
#ugroup3 (ugroup1 user5 user6 user7) ([user5, 16] [user6, 34] [user7, 15] [ugroup1, 40]) #()
ugrads (lancaster) - #-
End UserGroup

#Begin User
#USER_NAME MAX_PEND_JOBS
#user1 800 # user1 has pend threshold of 800
#ugroup1@ 500 # each user in ugroup1 has threshold of 100
#ugroup1 1000 # collectively ugroup1 has threshold of 1000
#default 100 # default, any user/group has threshold of 100
#End User

Begin User
USER_NAME MAX_JOBS MAX_PEND_JOBS
default 400 - # default, any user/group has threshold of 100
david 5 -
ugrads@ 5 -
End User
</syntaxhighlight>

* Update LSF once configuration applied
<syntaxhighlight>
addhost -u

# Or if your just giving a quick test in /opt/lsf/conf/...
badmin reconfig
</syntaxhighlight>

===== Limit Groups defined in Linux/OS =====
* NOTE: For groups defined in linux, LSF will only check the /etc/group file (so standard users supplementary groups only considered)
* The following will fail:
<syntaxhighlight>
atlasprod:x:10019:
lhcbusers:x:10020:
</syntaxhighlight>

* The following will be recognised by LSF
<syntaxhighlight>
atlasprod:x:10019:user1,user2,user3
lhcbusers:x:10020:user4,user5
</syntaxhighlight>

* Change the users groups
<syntaxhighlight>
usermod -g new_primary_group user (only updates /etc/passwd)
usermod -G additional_group user (adds entried to /etc/group)
</syntaxhighlight>

* Now make changes to lsb.users (in /etc/cfm/templates/lsf/...)
* NOTE: The @ symbol forces to limit to apply to each users, rather than the group as a whole.
<syntaxhighlight>
Begin User
USER_NAME MAX_JOBS MAX_PEND_JOBS
atlasprod@ 100 -
lhcbusers@ 200 -
default 400 - # default, any user/group has threshold of 100
End User
</syntaxhighlight>

* Verify these are configured correctly (after addhost -u or badmin reconfig)
