Hi all, We use Keycloak’s user federation to integrate with a (Windows 2012) Active Directory (AD) server. We want to store all users and groups in AD and also want to manage the password policies from AD so we do not have any password policies in Keycloak set up. We also want to use Keycloak for all user management functionality. We have set up the password policies in AD at the domain level where we connect to from Keycloak. Our password policies in AD are as follows: - password complexity (min length + special chars) - account lock out after 3 attempts - password history (not allowed to use previous 5 passwords) Users and admins can set and change passwords in AD from Keycloak fine. However the password policies do not quite do what we want them to: - Password complexity policy seems to work fine. - Account is indeed locked in AD after three failed attempts. However the ‘Unlock users’ functionality in Keycloak does not unlock the users in AD. Users can only be unlocked in AD itself it seems. We would like to be able to do this from Keycloak however (and really per user and not for all users in one go). Should this work in Keycloak or is this a new feature request?

- The password history policy does not seem to work at all. Users can currently set their password to a previous password without a problem. Does anyone have an idea why this policy in AD does not work from Keycloak?

Because: 1) Our current model SPI and federation SPI for update credential doesn't differ between the case when user is updating his credential or when admin is resetting the credential of user. 2) Also in LDAP both operations are executed under "admin" connection (user own connection is used just to verify his password). 3) Finally there is no old password available in the UserModel.updateCredential operation Feel free to create JIRA, but hard to promise when we will be able to look into it (I am on holiday next week and then we have feature freeze and won't be able to add new stuff like this). So if you really want it, you may need to send PR by yourself. The implementation may require more changes. Some pointers how I would do it (we may need ACK from other team members to confirm as we are close to "feature freeze" phase right now until we start on keycloak 2.x development): 1) Change UserCredentialModel and put new fields "oldValue" with the old password. Also maybe the boolean field "isAdminCall", which will be true if admin is restarting the password (in this case the LDAP operation can be same like already and use "replace" operation) or if user himself is restarting the password. Maybe the "isAdminCall" field is not necessary as with admin call, the "oldValue" simply won't be available (when user himself is restarting the password in account management, user is required to set password and AccountService knows the old password value) Other possibility is to introduce the context map ( Map<String, String> contextData ) on UserCredentialModel, which is more flexible. At the same time the "device" field can be removed from UserCredentialModel IMO as it doesn't seem to be used from anywhere right now. 2) Change the LDAPIdentityStore implementation to differ between the two cases you described Marek On 14/01/16 17:41, Edgar Vonk - Info.nl wrote: > Regarding the MSAD password history policy not being used when we change the user’s password through Keycloak (using Keycloak’s user account screen where the user is updating his/her own password): is this maybe not caused because in the code the change password request to MSAD is not done ‘correctly’? If I look at LDAPIdentityStore#updateADPassword it seems that changing the password involves a replace operation and not a delete + add operation? If I understand the documentation from Microsoft correctly I think you need to do a delete + add operation when the user changes his/her own password and the replace operation only when an admin changes someone else’s password. I think this might explain why the password history policy is not adhered to? > > From https://support.microsoft.com/en-us/kb/269190: <https://support.microsoft.com/en-us/kb/269190:> > "There are two possible ways to modify the unicodePwd attribute. The first is similar to a normal "user change password" operation. In this case, the modify request must contain both a delete and an add operation. The delete operation must contain the current password with quotes around it.

In order to do this, the client must bind as a user with sufficient permissions to modify another user's password. This modify request should contain a single replace operation with the new desired password surrounded by quotes. If the client has sufficient permissions, this password become the new password, regardless of what the old password was." > > > >> On 14 Jan 2016, at 12:09, Edgar Vonk - Info.nl <http://info.nl/> <Edgar(a)info.nl <mailto:Edgar@info.nl>> wrote: >> >> Ah, sorry about this.

Once the user has in MSAD userAccountControl of 514, he will be marked as disabled in Keycloak.
