Thanks for this update.
Would it make sense to introduce a new configuration directive to
indicate the the password is unsalted AND unprefixed? For example,
$wgPasswordPrefix = false ?
Work-arounds for connecting mod_auth_mysql to MediaWiki 1.13 include
these:
1. Modify crypt() in User.php (not ideal)
2. Modify and recompile mod_auth_mysql (not ideal)
3. Create a MySQL VIEW that returns user_name and the latter portion
of user_password (my current solution)
4. Introduce a new configuration directive, such as $wgPasswordPrefix
