Thanks!! Actually this should be very helpful, indeed.

I believe that I have figured it out. The root of the problem is that passwd structure on z/OS and OS/390 is rather different from that on Unix because there is no /etc/passwd on the mainframe. (The errors were caused by my somewhat naive patch was not consistent.) Perhaps to do a proper password authentication one has to integrate OpenSSH with RACF. However, the thread to which you have referred me seems to address this issue, too.
Climb to the top of the charts! Play the word scramble challenge with star power.
