Deploying Microsoft LAPS Part 3

In the last post we went through deploying the LAPS agent using a script, GPO or SCCM. The next step is to configure the GPO settings to apply LAPS management policy’s

First, we create a new GPO to apply the LAPS management policy’s, the LAPS policy’s are under Computer Configuration > Polices > Administrative Templates > LAPS (If this doesn’t show the ADMX template is probable missing and will need to be installed. This can be done using the LAPS installer)LAPSGP1Password settings policy used to set the password complexity, length and ageLAPSGP2Specify the account that the password policy will apply to if this is the default administrator account this should be left at defaultLAPSGP3LAPSGP4Enabled management of local admin accountLAPSGP5Once the policy is configured apply the policy against the required OULAPSPass1To confirm that all settings are working, run a gpupdate on a test device. Once applied we can check the password in a few different ways

First way is to run PowerShell command:LAPSPass

Second way is to use the LAPS UI , this can be either used from the management server or installed on local computer using the LAPS installer and selecting the LAPS management tools

The third method is to check the AD computer attribute ms-Mcs-AdmPwd:LAPSPass4

Last step is to set delegated access to a security group or set of users to view and reset the local administrator password. Use the below command to verify the current rights

Find-AdmPwdExtendedRights -identity:OU distinguishedName

LAPSPass5There are two command to set the rights, one for read and one for reset rights
