[cvsacl-users] How to permit a single file and deny others for a user?

[Lu J. <jx...@fu...>]

One of my friend, who serve as a team leader in an software company ask 
me for a solution to permit a single file and deny others for a user, 
who might just enter the team serveral days before a project's leadline.

So I tried to find the way (allow user "developer1" to access a file 
exer1/lib/hello.c and deny other access), but failed, here is the logs:

Server side:

[root@edusrv cvs]# cat CVSROOT/aclconfig |grep ^[^#]
UseCVSACL=yes
CVSACLDefaultPermissions=n
UseSystemGroups=yes
[root@edusrv cvs]# cat CVSROOT/access
f:exer1/lib/hello.c:HEAD:developer1!a:
d:ALL:ALL:root!p:
[root@edusrv cvs]# ls -al
