[horde] Wich applic. need Horde to authenticate User?

[Roman Langolf]

Hi @ all!

I installed last CVS-Version of Horde and I get error:

Fatal error: Undefined class name 'auth' in
/srv/www/htdocs/web5/html/horde/config/registry.php on line 60

I'm looked for PEAR-Modul Auth. But it says:

package `Auth_RADIUS' is recommended to utilize some features.

Ok, looked for Auth_RADIUS, the same, it need radius. But when I 
install radius, I get some other error...

running: phpize
Configuring for:
  PHP Api Version:   200x0x1x
  Zend Module Api No:   200x0xxx
  Zend Extension Api No:   200x1xxx
`phpize' failed

What's the problem?

best regards!
Roman
