I've got a directory that I've lost control over on an AFS system. According to the system adminstrators, my adminin subgroup (dsekt:admin) has rlidwka on the directory. I'm a member of this group (and I can list the members of the group and see my nick there) but I can't set its ACL.

The pts:

$>pts membership dsekt:admin     
Members of dsekt:admin (id: -6813) are:

And my klist:

Credentials cache: FILE:/tmp/krb5cc_56782
        Principal: taran@NADA.KTH.SE

Both dsekt:admin and the directory are on the NADA.KTH.SE node.

With AFS, Access Control Lists (ACLs) are used to set access rights on directories (not files). (ACL ref: http://www.angelfire.com/hi/plutonic/afs-faq.html#sub2.04 )

First, display the ACL on the directory: fs la $directory

For example: tweety@toontown $ fs listacl . Access list for . is Normal rights: fac:coords rlidwka system:anyuser rl

Second, look at the ACL and confirm that your AFS-ID is either in the ACL or is a member of any group in the ACL. You can check group membership with: pts mem $afs_group_name

Third, examine the AFS access rights (ref: http://www.angelfire.com/hi/plutonic/afs-faq.html#sub2.04 ) and confirm you have the access rights needed.

To administer an ACL, you only need the "a" access right. However, in practice, it's easier to have all rights: "rwlidka".

Fourth, confirm you have authenticated into your AFS cell and have an active token:

For example: elmer@toontown $ tokens

  Tokens held by the Cache Manager:

  User's (AFS ID 9997) tokens for afs@ny.acme.com [Expires Sep 15 06:50]
  User's (AFS ID 5391) tokens for afs@sf.acme.com [Expires Sep 15 06:48]
     --End of list--

It is possible in AFS to authenticate into more than one cell.

I'm not very familiar with Andrew, but as a general rule, some permissions are stored in the parent dir, you may need permissions there too.
