I have two servers: one CentOS 5.8 & one Solaris 10. Both are joined to my workplace AD domain via PBIS-Open. A user will log into the linux server & run an application which issues commands over RSH to the solaris server. Some commands are also run on the linux server, so both are needed. Due to the application these servers are being used for (proprietary GE software), the software on the linux server needs to be able to issue rsh commands to the solaris server on behalf of the user (the user just runs a script & the rest is automatic).

However, rsh is not working for the domain users. It does work for a local user, so I believe I have the necessary trust settings between the two servers correct. However, I can rlogin as a domain user from the linux server to the solaris server. SSH works too (how I wish I could use it).

Some relevant info:

via rlogin:

[user@linux~]$ rlogin solaris
connect to address 192.168.1.2 port 543: Connection refused
Trying krb4 rlogin...
connect to address 192.168.1.2 port 543: Connection refused
trying normal rlogin (/usr/bin/rlogin)

via rsh:

[user@linux ~]$ rsh solaris ls
connect to address 192.168.1.2 port 544: Connection refused
Trying krb4 rsh...
connect to address 192.168.1.2 port 544: Connection refused
trying normal rsh (/usr/bin/rsh)
permission denied.
[user@linux ~]$ 

relevant snippet from /etc/pam.conf on solaris:

I have not really seen anything useful in either system log that seem to be directly related to the failed login attempt. I've tail -f'd /var/adm/messages on solaris & /var/log/messages on linux during the failed attempts & nothing shows up. Maybe I need to be doing something else?
