Hi, my fault for the delay responding.. I'm running 2.0.0-M4-SNAPSHOT off the
trunk.
I'm trying to capture response controls in 2 cases and I cannot get either to
work.
a.) When I update the userPassword attribute and policy requirements are not met
b.) When the user logs in and policy threshold is exceeded. Expiry, history,
lockout, etc.
In both cases either the response controls are null or the response control
returned has no data. Details below.
I have created password request and response control classes that implement
javax.naming.ldap.Control
The interface method getId() returns "1.3.6.1.4.1.42.2.27.8.5.1" which is a
static member named OID.
The policy response class extends the request class.
I have a ControlFactory Class which implements javax.naming.ldap.ControlFactory
and is added to my environment like this.
env.put(LdapContext.CONTROL_FACTORIES,"com.my.MyControlFactory");
The interface method below in my control factory only tests for data.
public Control getControlInstance(Control ctl) {
Control result = null;
if (ctl.getID().equals(ControlPasswordPolicyResponse.OID)) {
if (ctl.getEncodedValue() == null) {
System.out.println("No data in response
control");
}
}
return result;
}
For example, when I try and update a password (that's in the history) the
following exception is thrown but the response controls are null
javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 -
CONSTRAINT_VIOLATION: failed for MessageType : MODIFY_REQUEST
Message ID : 2
Modify Request
Object : 'uid=1320256180937,ou=users,ou=int,o=cpro'

'
: invalid reuse of password present in password history]; remaining name
'uid=1320256180937,ou=users,ou=int,o=cpro'
Again if the supplied password is too short, I get the exception but the
response controls are null
javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 -
CONSTRAINT_VIOLATION: failed for MessageType : MODIFY_REQUEST
Message ID : 2

'
: Password should have a minmum of 3 characters]; remaining name
'uid=1320878789594,ou=users,ou=ext,o=cpro'
The OID in these exceptions is a Netscape V3 control
http://www.alvestrand.no/objectid/2.16.840.1.113730.3.4.html
Finally when the policy is set to expire after 30 seconds (ads-pwdmaxage=30)
and the user's password is older than this, a response
Control is returned, but is getEncodedData() is null. This same thing happens
when policy conditions are met and the login is successful.
Thanks for your help. Carlo

have fixed this issue. Server indicates the user about expiry by sending the
ppolicy response control after setting the value for timeBeforeExpiration
property to the time left before the password expires.
Note that this only happens if the user sent a request with ppolicy control
(OID - 1.3.6.1.4.1.42.2.27.8.5.1)

this is a bit strange, do you have some custom caching mechanism in place? OR
some custom authenticator implementation that doesn't inherit the
AbstractAuthenticator?

have fixed this issue, please verify with the latest trunk and let us know.
