Note Submitter: mzajonc at pomona dot edu ---- The way PHP5 creates session ids has changed. No longer are session ids always 32 characters. Rather it depends on how session.hash_function and and session.hash_bits_per_character are set in php.ini. The default now gives 27 characters. To go back to 32 change the function to 1 and and bits to 5 or function 0 and bits to 4. This problem is particularily relevant for people using custom session handlers. For example, it affects phpSecureSessions.
