I just completed an initial installation of i-doit 0.9.9-3 on a CentOS 5 box running  Apache/2.2.3, php 5.2.10, mysql  Ver 14.12 Distrib 5.0.77.  I've followed the automatic installation, pass all the tests and then try to login using admin account.  It appears to accept the username/password, displays window to choose german or english.  I've tried both languages, clicked next and I'm back at the login screen.  I can access the mysql databases using the idoit account.  Not certain what is happening and not finding where any logs are kept to troubleshoot.

I've uninstalled (including deleting mysql databases) and re-installed. Same behavior each time.

Any ideas?
