File System / Permission Issue
 

I have a question...

I have a about 10 folders to which i want to grant/deny access to several users. I know I can do this using group permissions. But I have a constraint which prevents me from using groups in this setup...

So, is there a way how I can assign/unassign permissions based on USERS only. like how we do it in Windows World by using the Security tab and adding users to which we need to grant/deny permissions...

you could chmod the folder so that others but the owner and the group can access the files.

thanks for the reply.
but i have 100 users who need diff access rights to ONE FOLDER, so just USER RIGHTS and GROUPS RIGHTS will not help.

Ok, i got something interesting here...

Linux Server with NFS v3 will grant/deny access rights to NFS clients based on the AUX GID's of the user.

But, a Solaris NFS v3 server takes in to consideration only the PRI GID on the user and ignores whatever rights he has been granted/denied based on his AUX GIDs

any idea on how to correct this?

I think what you need is ACL, which is supported as an option by most filesystems, provided your kernel was compiled with the appropriate modules enabled.

However, my experience tells me that permissions like this quickly become an unmanageable mess, and actually most administrators are even too lazy to correctly handle unix-type (so much simpler) rights.

There are a few useful cases for ACLs, and this may well be one of them.
