Users in CVS

[Jitender Singh Bhatia]

Hi all,

I am new to CVS.
I have just set up CVS on Solaris 2.6 machine, while logged in as root. 

As a root user, i was able to create a repository, and then checkout files
etc.
But when i tried to commit changes back to the CVS repository i got the
message saying :

# cvs -d /usr/local/mycvsrepo commit
cvs [commit aborted]: cannot commit files as 'root'            

Next, i logged in as a ordinary user, and tried running cvs. But this time i
get error message :

$cvs
Cannot execute cvs

I have checked cvs binary has execute permission for all.

What could be the problem ?

How are different users treated by CVS ? 
Do i have to create a unix users one for each person who will be using cvs ?

thanks
J.
