# Authenticate to the Bridge Client

### Run the Bridge Client

On Windows environments that are attached to a domain controller, Keeper Bridge will default to Active Directory authentication.  Otherwise, the Keeper Bridge will assume generic LDAP authentication.

{% endstep %}

{% step %}

### Login to Bridge Application

* **Domain\User Name**: Input the domain and AD\LDAP username of the user that is a member of the **Keeper Admins** group created in the prerequisites.
* **Password**: Input the password of the user.
* **Use Global Catalog**: In multi-domain forest configurations you should uncheck **Use Global Catalog** option otherwise keep it checked to locate the username in the Global Catalog.
* **SSL**: If using Secure Socket Layer (SSL port 636) for LDAP authentication ensure the SSL box is check. If not, ensure the check box is not checked to use standard LDAP authentication (port 389)
* **Settings**: If the client is running on a different computer than the service, select Settings to specify the hostname and port of the Keeper Bridge Service.  (The Setting button will be grayed out while app is connected to the service.  To access settings stop the service).
  {% endstep %}

{% step %}

### Select Login

If you get a Login Failed message, it means either of the following:

* The username/password is not correct
* The user is not a member of the **Keeper Admins** Security Group
* The server does not support SSL and SSL is checked
* The username was not found in the Global Catalog. In multi-domain forest configurations if the Keeper Admins group is a Global Security Group the **Use Global Catalog** option should be unchecked or the Keeper Admins group can be made to be a Universal Security Group. In a multi-domain forest only users in Universal Groups are added to the Global Catalog.
