I'm trying to set up polyinstantiation of the /tmp directory using RHEL5. The /etc/security/namespace.conf file shows the following line as needing to be uncommented out: /tmp /tmp-inst/ level root,adm
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The documentation is a little bit outdated.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".
