Description Russell King 2011-05-04 09:10:05 UTC
SELinux is preventing /usr/kerberos/sbin/klogind from read, write access on the file krb5cc_p2991.

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

If you believe that klogind should be allowed read write access on the krb5cc_p2991 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep klogind /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-05-09 16:27:31 UTC
Miroslav I think we want to remove remote_login_tmp_t and replace calls with


userdom_manage_user_tmp_dirs(remote_login_t)
userdom_manage_user_tmp_files(remote_login_t)
userdom_tmp_filetrans_user_tmp(remote_login_t, { file dir })

Since this file should be created as user_tmp_t.
