Hi Michael,
the md5 encryption is new from RedHat 6.x which Cobalt RaQ3 is built
upon...
The only thing we have to do is update to the glibc/pam/passwd and all the
other stuff redhat has updated for the x86-platform for Cobalt and port
them to MIPS (NOT!)...
It's quite a big deal, I'm sorry to say. It's doable, but makes no real
sense today...
Best regards,
Rickard Osser
