Hi,
I am using Openldap,spring security 3.0.5,cas-server-support-ldap-3.4.8.jar. I am trying to do cas server authentication against open ldap. Once I get the DirContext object, I am trying to get PasswordPolicyResponseControl object using the following code.

for (final String dn : cns) {
String finalDn = //calling a method to get finalDn;
try {
this.log.debug("Performing LDAP bind with credential: " + dn);
DirContext test = this.getContextSource().getContext(
finalDn,
credentials.getPassword());
log.info("BindLdapAuthenticationHandler test:");
if (test != null) {
PasswordPolicyResponseControl pPolicyRespCtrl = PasswordPolicyControlExtractor.extractControl(test );
log.info("BindLdapAuthenticationHandler checking expired: "+pPolicyRespCtrl.isExpired());
log.info("BindLdapAuthenticationHandler checking locked: "+pPolicyRespCtrl.isLocked());
return true;
}
} catch (final Exception e) {
// if we catch an exception, just try the next cn
} finally {
LdapUtils.closeContext(test);
}
}



But I am getting the following exception at the line
PasswordPolicyResponseControl pPolicyRespCtrl = PasswordPolicyControlExtractor.extractControl(test );

java.lang.IllegalArgumentException: resourceOperatedUpon cannot be null

Any idea what I am doing wrong here. Cas server I am using is cas-server-3.4.8

Thanks in advance,
