Description Nicolas Mailhot 2010-12-11 09:53:22 UTC
SELinux is preventing /usr/libexec/polkit-1/polkit-agent-helper-1 from 'write' accesses on the file /var/lib/abl/users.db.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that polkit-agent-helper-1 should be allowed write access on the users.db file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep /usr/libexec/polkit-1/polkit-agent-helper-1 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

allow policykit_auth_t var_auth_t:file write;

Comment 1 Miroslav Grepl 2010-12-13 12:01:22 UTC
Does it work with

# grep -r policykit_auth_t /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 2 Daniel Walsh 2010-12-13 14:31:49 UTC
Probably should be allowed.

Comment 3 Miroslav Grepl 2010-12-13 14:53:43 UTC
Yes, added to selinux-policy-3.9.10-11.fc15.
