what is the use of /etc/project file and project administration commands?

i have two doubts..

1. what is the use /etc/project file. i renamed this file and when i tried to switch user or login with some user account the login was happening slowly. but when i renamed it to original name it was working fine... why so?

2. unix already has useradd and grouadd for user administration. what is the use of project related commands like projadd projmod.. which scenario i would be needing it.

Thanks in advance

I don't know why logging in was slow after renaming the /etc/project file. As for the purpose of project concept - it is needed for the resource control on a server where multiple applications share limited resources. It is to prevent situation in which one very "hungry" application takes away all the CPU time or memory or other resources present on the server, making it impossible for other applications to run properly.
