hi list! probably encountered by many, and mentioned a few times on this mailing list, but AFAIK never actually fixed - i just downloaded the latest stable release 2.0.1 and tried it with PHP 5.3.6-13ubuntu3.3 in Ubuntu 11.10. Create the default DB, log in with siteadmin/CHANGE, change the password. It fails right away and won't let you in any more. The below thread mentions a hack to disable salt. Doesn't seem like the right thing to do, and didn't help me either. http://users.exim4u.org/Fwd-Re-crypt-field-not-been-populated-during-user-cr... A short dig into the code shows that crypt_password('any string') with the default MD5 method returns a 200 symbol line instead of the old 48 symbols, probably due to the new MD5 code in PHP 5.3. The problem here is the default exim4u database schema: crypt varchar(48) default NULL, The default field size is simply too short - the new encrypted password was not saved properly, which killed it. Increase crypt to varchar(255) and it'll work right away. No code hacking necessary. I believe this should be updated in the installation SQL file as well.
