My original question:

>> I'm trying to configure C2 to work with NIS but I cannot make that the r>>pc.yppasswdd works...
>> I have to different files for passwd: /etc/passwd for normal passwd and >>/etc/passwd.NIS for NIS passwd so I'm running
>> /etc/rpc.yppasswdd /etc/passwd.NIS /etc/security/passwd.adjunct
>> When I try to change a NIS passwd I just get
>> Error from cosmos: Password incorrect

The solution:

        I install the patch 100564-07 (C2 Jumbo patch) and works pretty well with the following changes to the install instructions:

        1) You must put the AUyppasswdd and AUpwdauthd in the NIS passwd file
           and not in the normal passwd file.

        2) You must run /usr/etc/rpc.yppasswdd /etc/passwd.NIS -m passwd instead
           of /usr/etc/rpc.yppasswdd /etc/passwd.NIS /etc/security/passwd.adjunct -m
           I still don't understand why because I think is the same but doesn't work
           with the second sintax.

        3) The first time you're going to setup the passwd for a user the passwd field must be in blank
           in the NIS passwd file ...after the passwd is written to the /etc/security/passwd.adjunct
           you must put the ##login_name in the NIS passwd file.

Thank you very much to:
