8. NexLog Access Bridge¶
NexLog Access Bridge (NAB) is a feature that allows a user to access media from multiple recorders (NAB Source), using a single recorder (NAB Base).
For NexLog Access Bridge to work smoothly, the Base and Source recorders should all be configured with the same Authentication Mode.
8.1. NAB with Active Directory¶
If the NAB Base and all NAB Sources are configured with Active Directory authenticaton in the same domain, login attempts will work smoothly. Each recorder included in the NAB network should be joined to the domain using a unique hostname and service account.
When creating the service accounts, be sure to enable delegation as shown in Figure 6.4 of Section 6.6.2: Set Service Principals.
If the NAB Base is joined to the domain, but the NAB Source is not, it will prompt for a login and you can enter the appropriate credentials to log into that recorder.
8.1.1. NAB with Single Sign-On¶
If Single Sign-On is enabled on a NAB Base, then ideally, all of the recorders involved in the NexLog Access Bridge network should be configured to use SSO as part of the same domain. That way, the login experience will be smooth.
If the NAB Base is configured for Single Sign-On, and the NAB Sources are not, then any SSO log in will fail back to the standard log in prompt when connecting to those sources.
The more complicated situation is the reverse. If the NAB Base is not configured for Single Sign-On, but a NAB Source is, then the NAB Source will require specific configuration to allow the connection to happen.
This might happen in a situation where your NAB Sources are all on one network and domain, but the NAB Base is remote or on a different domain.
In this case, an administrative user on the NAB Sources must create an exemption for the NAB Base to connect to its database.
See Section 8.3: NAB Base Database Exemption for how to create the exemption.
8.2. NAB with SMB¶
If the NAB Base is configured for SMB Authentication, each NAB Source it is connected to should also be configured for SMB authentication.
If the NAB Source is unable to be configured for SMB authentication, you must create an exemption for the NAB Base.
See Section 8.3: NAB Base Database Exemption for how to create the exemption.
8.3. NAB Base Database Exemption¶
When a NAB Source is unable to be configured for SMB, LDAP, or AD authentication due to network topology or configuration, a database exemption may be required.
The user must still have an account on the NAB Sources.
Fig. 8.1 NAB Base Database Exemption¶
To create an exemption, login to the web configuration manager on each NAB Source and navigate to .
Enable the checkbox for Exempt NexLog Access Bridge Hosts from Database Authentication.
In the field provided, enter the IP address of the NAB Base users will log in from. If the NAB network has a redundant Base, enter the IP address for each Base separated by a comma (,).
Save your changes and reboot the NAB Source.
