password length

Is there a limitation on the length of passwords?
Any users i add with a password of more than 8 characters, can log on only
using the initial 8

This happens both when logging into photon, or logging in remotely with ssh

Is this documented somewhere?
My system (uname -a): QNX localhost 6.2.1 2003/05/17-02:28:40edt x86pc x86

On a side note, i got a couple of sshd errors in syslog that i have not yet
found much info on. Any help or pointers in the right direction would be
