I'm trying to set up polyinstantiation of the /tmp directory using RHEL5. The /etc/security/namespace.conf file shows the following

The /usr/share/doc/pam-0.99.6.2/txts/README.pam_namespace file
describes
the format of the /etc/security/namespace.conf file, and the
allowable
values. For the <method> entry it lists the following valid values: "user", "context", "both". It doesn't list "level" as a valid value. However, "level" is the only value that I can get to work. With
"user",
"context", or "both", I get the following error when I attempt to
use
newrole to change the level of my shell: "pam_open_session failed with Cannot make/remove an entry for the specified session"
Any ideas as to why?
There can be various reasons. Use the 'debug' option of pam_namespace
to
get some debug messages in /var/log/secure which may give some more insight on this.
And what other values are valid other than "level"
The documentation is a little bit outdated. The valid values are
"user",
"context" and "level".
Could you explain the difference between "level" and "context"? Here is what I'm seeing:
If I have "/tmp /tmp-inst/ level root,adm" in the namespace.conf file, when I use the command "newrole -l s4:c10,c20", I get the following entry under the /tmp-inst directory: system_u:object_r:tmp_t:s4:c10,c20-s4:c0.c255_mr_clarkson. This entry contains both my name as well as the full security context of the shell that I've newroled to (the destination shell).
If I have "/tmp /tmp-inst/ context root,adm" in the namespace.conf file, when I use the command "newrole -l s4:c10,c20", I get the following entry under the /tmp-inst directory: system_u:object_r:tmp_t:s0-s15:c0.c255_mr_clarkson. This entry contains both my name as well as the full security context of the shell that I've newroled from (the origination shell).
Is this the expected behavior?
Thanks
