automatic LDAP authentication for web application

[Raguraman Thiru]

Hi,

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.

I've used JCIFS in the past, but that's a bit outdated. They acknowledge it though, and their website somewhere mentions better alternatives: http://jcifs.samba.org/src/docs/ntlmhttpauth.html

Note that your browser must cooperate. Firefox will keep asking for the credentials unless you add the site to the "network.automatic-ntlm-auth.trusted-uris" configuration parameter. Opera always asks for the credentials, although it can remember them (so can Firefox). I can't really remember what Chrome does.
