Package: kscreensaver
Version: KDE 2.1.0 
Severity: normal
Installed from:    Other
Compiler:          Compaq C++ v6.3
OS:                Other
OS/Compiler notes: Tru64 5.1

I'm running Tru64 Unix 5.1 with enhanced security installed and running. I installed \
KDE2.1 on my system from the kde.org weblink. The problem is that many of the \
screensavers do not work to begin with. Only the basic ones like blob actually start. \
When I'm logged in as root, the screen will lock and will unlock when I type in my \
password. However, when a normal user locks their screen, it will not unlock when \
they type in their password. I would presume that this is an authentication problem \
in the code that interfaces with the SIA subsystem. I've helped patch xlockmore for \
the SIA subsystem. I have the SIA logs enabled, and it does not show a successful \
connection with the SIA system when the screensaver tries to authenticate. Here is \
some sample code as to how the SIA subsystem works:

#include <siasecurity.h>

int main(int argc, char *argv[])
{
 int myargc = 1;
 char *myargv[2];
 char *user   = "someusername";
 char *pass   = "yourpassword";
 int auth_stat;
 myargv[0] = "yourapplicationname";
 myargv[1] = NULL;
 set_auth_parameters(argc, argv);
 if (argc != 3) {
        fprintf(stderr, "usage: %s username   
        password", argv[0]);
        exit(1);
 }
 user = argv[1];
 pass = argv[2];
 auth_stat =
sia_validate_user(NULL,myargc,myargv,NULL,user,NULL,0,NULL,pass);

if (auth_stat != SIASUCCESS ) {
 printf("No go %d", errno);
 perror("");
 }
printf ("Done");
}

% cc -g -o siavaluser siavaluser.c -lsecurity
% ./siavaluser username password

The only solution I have at the moment is to kill the screensaver processes or to \
kill the entire xsession. Or use another screensaver program like xlockmore or \
xscreensaver. It would be nice if this worked properly. If you need for me to try \
some things out, please contact me.
