mysql upgrade problem 3.23 - 4.1

[mikerh9]

I upgraded mysql mysql-3.23.58-1 to mysql4.1

In mysql-3.23 ( I have this field)
password | varbinary(45) | YES | | NULL
|

I inserted data into this field as password('pass').

I have php script that checks if login valid. mysql-3.23 and
mysql-4.1 have identical data.

It worked on mysql-3.23 but doesn't work on mysql4.1. Password don't match.

Any ideas why?
