Fwd: [MLS Policy]:- Problem for mapping between the Linux user to SELinux user for fedora 8

Hi...

Now I am trying to configuring RBAC using MLS (Multilevel Security) Policy
for fedora 8.
Because i have read danwalsh jornal he side MLS policy is more use full for
RBAC.

Using RBAC In FC5/MLS Policy*

So i am using MLS policy for RBAC. Here i have installed MLS packages and
changed to targeted policy in to mls policy.
Then i have configured the roles for users but i couldn't set the roles
because when i am setting the roles it will display the error message.

Steps to reproduce:

1) Adding the SELinux audit user using semanage command.

# semanage user -a -R staff_r -R auditadm_r -P staff audit_u

2) Here i am checking SELinux user.

[root@turtle2 ~]# semanage user -l

Labeling   MLS/       MLS/
SELinux User    Prefix     MCS Level  MCS Range                      SELinux
Roles

audit_u         staff      SystemLow  SystemLow                      staff_r
auditadm_r
root            sysadm     SystemLow  SystemLow:SystemLow-SystemHigh
system_r sysadm_r staff_r secadm_r auditadm_r
staff_u         staff      SystemLow  SystemLow:SystemLow-SystemHigh
sysadm_r staff_r secadm_r auditadm_r
sysadm_u        sysadm     SystemLow  SystemLow:SystemLow-SystemHigh
sysadm_r
system_u        user       SystemLow  SystemLow:SystemLow-SystemHigh
system_r
user_u          user       SystemLow  SystemLow
system_r user_r
[root@turtle2 ~]#

3) Now i am setting the Linux user to SELinux users, when i am setting the
SELinux user it will throw the error message as follows.

[root@turtle2 ~]# semanage login -a -s audit -r SystemLow-SystemHigh prakash

libsemanage.validate_handler: selinux user audit does not exist No such file
or directory.
libsemanage.validate_handler: seuser mapping [prakash -> (audit,
s0-s15:c0.c1023)] is invalid No such file or directory.
libsemanage.dbase_llist_iterate: could not iterate over records No such file
or directory.
/usr/sbin/semanage: Could not add login mapping for prakash
[root@turtle2 ~]#

4) I am using sysadm_r  root information as follows

[root@turtle2 ~]# id
uid=0(root) gid=0(root)
groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)
context=root:sysadm_r:sysadm_t:SystemLow:SystemLow-SystemHigh
[root@turtle2 ~]#

5) This is i am getting audit log messages using ausearch command.

[root@turtle2 ~]# ausearch -i -m AVC -sv no
type=SYSCALL msg=audit(06/02/2008 22:09:05.165:6877768) : arch=i386

scontext=system_u:system_r:rpm_t:s0-s15:c0.c1023
tcontext=system_u:object_r:inotifyfs_t:s0 tclass=dir

I don't know why its throwing this error. I have searched in to google but i
couldn't find.

Please help me what should i do.

Thanks,
Prakash
