Problem in output to a process in perl

Hi All,
I am trying to get a kerberos ticket with the help of a perl script, so that it is automated. The script works in Redhat however in Suse, I am encountering problem, where the kinit process waits for user input, however the requirement is that it should not wait as I am writing the password to STDIN of the process.
Here is my code, as I am quite new, I must not be doing the right thing here. ne help would be most thankfull.
#!/usr/bin/env perl
use warnings;

open (WTR, "| kinit Administrator\@IN.CAL 2> error.txt");
print WTR "password\n";
print WTR "\n";
close WTR;

after the open statement, you should check to see if there are any errors returned before you try wring the data. My guess is that you have some sorta permissions problem and the WTR file handle is invalid, resulting in the output going to STDOUT

Thanx for point it out, however its very specific to the way heimdal kerberos library behaves... The same script works fine in RedHat, only in Suse it gives a problem, there are no errors

echo "freevision" | kinit Administrator@IN.CAL

this should work, but it does not!
