I can't manage OpenID to work. When a user logs using an OpenID address, a blank page appears.
In the SSO module, I have a warning about LDAP not being installed. I think OpenID uses some kind of LDAP also. Does OpenID need LDAP, as SSO does?
(If I need LDAP support, there's nothing to do, since it needs to be compiled into php -- a external LDAP pear package does not work).
