[TYPO3] Single Sign-On Extension

[Fabio ex Typo3 n00b]

Someone use it? with typo3 4.0?

I installed it on typo3 4.0 and seems to have some problems, when I 
log-in fe typo3 and I try open the page with the plugin installed I got 
(Fatal error: Maximum execution time of 30 seconds exceeded in 
c:\programmi\easyphp1-8\www\typo4\typo3conf\ext\naw_single_signon\pi1\class.tx_nawsinglesignon_pi1.php 
on line 95)

When I click on Usermapping in the BE, nothing happen ( maybe with typo3 
3.8 works ).

What I need to do is:

Have Typo3 and eGroupware on the same server, and use twice with a 
single login in Typo3 FE

Any solution to do this?

Thanks All
