[TYPO3-linux] Typo3 update from 6.2.0 --> 6.2.2

[Anne Arlt]

Hello,

I have a problem with my typo3 installation. I update the system from 6.2.0 ---> 6.2.2.
After update I can't login in the backend.

Output of php_error_log:
Before update to 6.2.2
[22-May-2014 10:46:29 Europe/Berlin]  - saltedpasswords: BE Authentication successful for username 'admin'

And after update to 6.2.2
[22-May-2014 10:47:16 Europe/Berlin]  - Core: Login-attempt from (), for username 'admin' with an empty password!

My system:
Linux  2.6.32-358.18.1.el6.x86_64 #1 SMP Wed Aug 28 17:19:38 UTC 2013 x86_64
Apache/2.4.4 (Unix) OpenSSL/1.0.1e PHP/5.4.16 mod_perl/2.0.8-dev Perl/v5.16.3
Mysql Server Version: 5.5.3

I can't detect reasons for this problem.

Thanks, Anne Arlt
