changeuser doesn't edit the keys file directly; it uses keyfs.
Probably rewhack your auth server by losing the keys file and try
again.  Make sure keyfs is actually decrypting the keys file
correctly.  If the password you give at boot is wrong, it won't
be able to do this.  ("Wrong" means "not the same key that it waas
using when it wrote the file".)  Look in your logs for messages from
keyfs.

Did 3/27/01 upgrade has anything to do with it?

Also, what happens if I just remove adm/keys and /adm/keys.who and
recreate them with auth/changeuser???

[Alexander Povolotsky]

When I am creating a new user (say guest) using auth/changeuser  I could see
this message Ishwar mentioned:
keysfs: bad status key in file

But at least it creates the keyfile and creates the password ...
For already existant users (glenda, adm, sys etc ) I somehow lost keys at
some point (do not remember exactly how ...)
and now if  I am trying to recreate keys for those users using
auth/changeuser - it fails with the error message:
changeuser: can't create user "such and such": access permission denied.
By the way, I do not have password set for those preexistant ones - how I
could set password for those ?

So, anyway, now I could reboot the system and log as guest with supplying
the password ...
Ok, I am looged in ...

Running auth/keyfs -p
Password: <such and such>

Works ...kind of ... but with the warning again: bad status in key file ...

Ok ... going further ...

aux/listen tcp
auth/listen -t /rc/bin/service.auth

No errors or warnings ...

Now I am starting the drawterm on my Solaris machine:

yarmouth$ drawterm -a 135.17.241.14 -c 135.17.241.14
default depth=8
yarmouth$ !!
drawterm -a 135.17.241.14 -c 135.17.241.14
default depth=8

The drawterm window shows up with user "none" - changing to guest ..
Supplying the password ...

Getting  ...
?AS protocol botch: file does not exist.

Any hints ?
