You might want to think about separating code and conditions. This way, you can permit other people to modify conditions without accessing the code. for Kixtart 4.x I would recommend using a .INI file that contains the condition. Example:
code:
.INI file:
[Conditions]
SpecialUsers=user1,user2,user3

code:
Kixtart code:
$specialusers=split(readprofilestring('conditions.ini','Conditions','SpecialUsers'),chr(10)
for each $user in $specialusers
if $user=@USERID
; do something
endif
next

Alternatively, if you need certain conditions based on user names, you could arrange users in a group on the domain controller and check whether a speciifc user is member of that group. Example:
Create a group 'Special Users' with group members 'User 1' and 'User2' on the domain controller
code:
if ingroup('Special Users')
; do something
endif
