locking certain slots

[deadlyfudger 1]

Hello i run an island life server. We have 4 slots on the civilian side which are admin slots. I would like to know how i can lock those 4 slots to certain PIDS. Island life has 3 teams, Blufor (cops)/Civs/ESU. I would also like to lock some cop slots to trained officers only by adding there PID. Is there a certain script i can use for this? Please help

admins = ["UID1","UID2","UID3","UID4"];
if (!(getPlayerUID in admins)) then

titleText ["Admin Slot! Kicking in 20 Seconds!", "BLACK"];
sleep 5;
titleText ["Admin Slot! Kicking in 15 Seconds!", "BLACK"];
sleep 5;
