I am not sure b'cause I didn't do it neither. But I can show you some light. Basically, If you know how to configure LDAP authentication with Weblogic, it is same for any ldap servers. ADS, like any other LDAP server, can be configured for SSO.
I am sure there may be some changes with OU settings (for example, ADS it is , "ou=users,cn=people,dc=example,dc=com"
I think there are some little docs available for this. Here is one of the link I found useful.
