The cause of this 2.9 issue was usually an unreadable "temporary"  
session file in /home/httpd/perl/tmp (e.g., $uname_$dom_$cid.db, where  
$uname is username, $dom is domain, and $cnum is the LON-CAPA internal  
course "number").

This issue is fixed in lonuserstate.pm rev 1.137, which is included in 2.10.0.

A solution on a 2.9 server was to delete the particular user's session  
files in /home/httpd/perl/tmp

$uname_$dom_$cid.db
$uname_$dom_$cid_params.db
$uname_$dom_$cid_symb.db
$uname_$dom_$cid.state

and then re-select the course from the roles screen.

I have not heard any reports of a recurrence of this behavior in 2.10,  
following the lonuserstate.pm 1.137 change.
