Can't scp from HPUX to AIX

I'm trying to scp a file from HPUX (OpenSSH 3.7.1P2) to AIX (4.0).  It
asks me to authenticate, I type in the password and after three attempts
it fails with "no more authentication methods to try".  I know I'm not
typing in the password incorrectly because I can telnet fine.  Same
problem happens with ssh, obviously.  However, everything works fine in
the direction if I scp from AIX to HP-UX.

Any ideas??

Thanks!!
