dear aix gurus,
what is the different between administration group in aix. we have one user that have one primary group and a secondary group.

1. id pkiwas

uid=602(pkiwas) gid=400(wasgrp) groups=14(nfast)
but the wasgrp, the group administrative is false and nfast is true. what is the impact when they create file. if we created a new file with this id, the group of the file always assigned to secondary group instead of primary group. is it because of the administrative group for primary is false and administrative for secondary group is true. hope to hear from you. thank you

I believe what you're seeing is the result of directory permissions. It's been a long time since I looked, but I believe the administrative flag doesn't affect which group is assigned to the files created, it's more likely the directory you're creating files in is owned by that group and has the SGID bit set. i.e. the directory permissions will have a capital S where the group x would usually be, like this

drwxrwS--- 2 bob system 512 16 May 15:41 dirname

Any file created in that directory will be owned by user:system
