HP-UX Secure Shell A.03.81.002 on two machine but sshd is different

[breiner]

Hello,

I've installed HP-UX Secure Shell A.03.81.002 on two machine HP 9000/785 HPUX 11.00.
On the machine A, I run the command :
strings /opt/ssh/PA-RISC2.0/sbin/sshd | grep pam.
The result is: keyboard-interactive/pam
On this machine sshd works very well.
On the second machine B, I run the same command :
strings /opt/ssh/PA-RISC2.0/sbin/sshd | grep pam.
The result is :

/usr/lib/libpam.1

sshd on this machine give me an error PAM conversation failure.

The sshd of each machine are configured with UsePAM yes.
I would be great if someone could help me.

On the malfunctioning machine:

swremove secure shell

swinstall it again.

I don't have an explanation, but this should resolve the problem.

I've made this before I write to you but that change nothing.

I had the same problem on a HP-UX 11.00 host.
On another host it worked.
The difference was the patchlevel.
Check the recommended patches! See http://www.docs.hp.com/en/T1471-90011/ch01s08.html#babjebhg
On a system with current patches everything works fine.
