Comment 5 Marcus Meissner 2005-06-22 16:16:49 UTC 
patchinfos submitted, only containing "heimdal" itself, since this is the 
package with "telnetd" inside.
Comment 6 Marcus Meissner 2005-07-05 11:45:22 UTC 
Hi, 
 
qa can not approve the maintenance update of heimdal because we currently can 
not reliably test the telnetd and sshd part. 
 
Sometime it works, sometime not. 
Please assist in debugging this. 
 
The testcase we ran are 
http://pdb.suse.de/pdb-testcases.pl?Package=heimdal&Release=27&tcid=5770 
 
The current status can be read in 
~rommel/QA/patch-10262/log 
 
The failures seem to be independent of architecture and code base. 
Even re-running the testcases on the same host (including re-creation of the     
complete Kerberos setup) does provide random outcome. 
 
I'm totally lost.
