Spring Ldap - User Authentication

[Nick_Andy]

Hi,

I am trying to authenticate a user with his userid and password through Active Directory. I do not know to which group the user belongs and also dont know the whole CN or DN. Is there a way through Spring LDAP that we can authenticate a user just based on their user name (sAmAccountName) and password.

Thanks for your help.

Using with the sAMAccountName you can construct a filter which will uniquely give you a single entry. Use this filter as input to one of the authenticate methods of LdapTemplate and you should be all set.

Hi Rasky,

Thanks for your inputs. I tried below code but its giving me an error. The problem seems to be bcoz of missing group name. Is there any wild card characters that I can use to allow it to check all the existing groups in AD?

ldapTemplate.authenticate("", ("sAMAccountName=<userid>"), "<password>")
