[rsbac] ACLs / acl_grant Problem

[jochem_ippers at email.de]

Hi again,
when I try to change an acl nothing seems to happen; for example (existing file and existing user) when I do: 

acl_grant -v -k -u jochem LOCK FD /tmp/hallo 
Revoke rights: 00000000010000000000000000000000000000000000000000000000000
for USER 1001
Processing FD '/tmp/hallo'

nothing changes (same with the -m option), LOCK right is still there:

acl_rights -u jochem FILE /tmp/hallo
acl_rights: User 1001
/tmp/hallo       00000000010000000000001110100000011011010010111111110110100

I compiled rsbac version 1.2.5.1 (rsbac-admin-tools 1.2.5.1) for kernel 2.6.14. I tried different compile combinations, at the time I try a kernel with ACL as the only security module.
(Do I have to prepare something before using the ACL or any other module?)
Greetings
Jochem
