If you use Active Directory authentication and are using Open-AudIT 1.12 it will likely be failing.
If you do not use Active Directory authentication, this should not affect you.
This will also only affect Active Directory validated logins to Open-AudIT Enterprise (not Community).
You can confirm this by viewing the apache log. It will contain entries like the below.
To fix this issue (before we release 1.12.2) you can edit the file:
Linux - /usr/local/open-audit/code_igniter/application/models/m_userlogin.php
Windows - c:\xampplite\open-audit\code_igniter\application\models\m_userlogin.php
You need to remove the clean_sql function, so please replace line 47 with the below.
And please replace line 126 with the below.
This bug has already been fixed for our next release. Apologies for any inconvenience caused.
