Dollar Universe needs the SUID on uxdqmlan (in bin folder) to run the jobs with a specific submission account (only true when the node owner is different than root).
When trying to execute a Job with a specific account (different than administrator), you will see the error below :
2021-04-01 11:30:00 |WARN |X|DQL|pid=24553.4159825600| o_dqm_is_user_allowed | testaccount forbidden (non-privileged mode)
Release : 6.10
Component : DOLLAR UNIVERSE
The "NOSUID" option is set on the FS where the node is installed : there won't be any way to use any Submission account different than the default one (administrator).
Never use the "NOSUID" option.
Dollar Universe is meant to switch the user using "su - <LOGIN>" and the SUID on uxdqmlan.
