Can one of you guys take a look at this?

Same problem here, so probably not account specific. Flash message show success.png image, which make the message bit confusing too and easy to miss on the first try ;).

This is probably what we get for running OpenSSL's "The ca command is effectively a single user command" CA on the FAS server :-(

{{{
Write out database with 1 new entries
unable to rename ./serial to ./serial.old
reason: Permission denied
unable to write 'random state'
}}}

A second look indicates that this might be an SELinux problem. CCing lmacken.

{{{

Sorry, I pasted the wrong lines:
{{{

}}}

Thanks for reporting this - this should be fixed now (SELinux has temporarily been set permissive on fas1). We'll need to get some rules in for permissions for the FAS user on /var/lib/fedora-ca, which lmacken is working on for after the change freeze.
