I have a requirement of implementing LDAP based automatic windows authentication for a application deployed in tomcat 7. The requirement is, when I try to access the application page it should take the windows login credentials for authentication process and should not prompt user to enter the credentials. I had came across JNDI realms and various authentication types like BASIC, form based ,digest,etc. From my study I think all are prompting user to enter the credentials.
Is there any other way to achieve my requirement? All the client systems are in Intranet domain and user details stored in LDAP server.
Yes, there is a Realm that hooks directly into the existing Windows authentication. I don't remember its name or where you can get a copy of it, but it is available. Ask Google.
I should caution you that unlike other Realm modules, you cannot just plug it in and go, however. For one rare time in its existence, Microsoft actually set security control "on" by default; each IE client that uses this Realm has to have a switch flipped to enable it to participate.
