Credentials not recognized.

[Pavan K]

Hi All,

I am trying WEB SSO using shibboleth service provider and identity provider.
I have installed and configured them. Request from Service provider is
getting redirected to Identity provider. And when i am trying to login from
identity provider i am getting "Credentials not recognized" message.

I am using "UserName PAssword handler" using LDAP. Here is my <LoginHandler>
configuration,

*
    <ph:LoginHandler xsi:type="ph:UsernamePassword"

jaasConfigurationLocation="file://c:\agiliance\saml\idpinstall/conf/login.config">

<ph:AuthenticationMethod>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</ph:AuthenticationMethod>
    </ph:LoginHandler>*

And here is my "login.config" file


*ShibUserPassAuth {

edu.vt.middleware.ldap.jaas.LdapLoginModule required
      ldapURL="ldap://**<LDAPHOST>:**<LDAPPORT>"
      baseDn="ou=**ABC,dc=**XYZ,dc=**com"
      ssl="true"
      userFilter="**uid={0}";
};*

And i am using default "login.jsp" file. I did not customize that file. I
have tried different options for *"ShibUserPassAuth"* but no luck. I am
getting null pointer exception in logs. Please look at the logs below.

Can anyone please let me know what i am missing here. Please help me to
resolve this issue.

Thank you in Advance.
