9 character passwords invalid?

With the advent of Solaris 9 and the end of the 8 character limitation on
passwords, I have started to gradually increase the length of the passwords.
I am doing is slowly to make sure nothing breaks.

Well, I think something has.

On the few solaris 9 servers that have 9 character root passwords, it is
impossible to go to single user mode. When prompted for the root password
to enter single user mode, the 9 character password is not recognized.
The first 8 characters of that 9 digit password were also not recognized.
It was necessary to bring the box back up to multi-user mode, change the
root password to an 8 character password and then go into single-user
mode. The server accepted the new 8 character password just fine.

btw, on these servers I have changed the default algorithm from DES
(__unix__) to blowfish. However changing the password, still in blowfish,
to 8 characters resolved the problem so I do not believe its the algorithm.

So has anyone else seen this behavior where on a Solaris 9 server a root
password of more than 8 characters is not honored when entering
single-user or maintenance mode? TIA.
