database permission

[Grass 4.1]

Hello,

I have set GRASS up on our SGI.  The software is now to the point
where users are using it.  I have run into a problem.  It turns 
out noone can access any of the mapsets in any of the locations
except user grass, the account I used to set up the GRASS software.
I have set the permission on the database directory to 777 and still,
noone can access the data.  Does anyone know what the problem is?

Thanks,
