a first management service that is coupled to the first enclosure controller via a second communication channel and to each of the at least one first I/O module via a third communication channel, wherein the first management service is configured to:

retrieve the master I/O module secured access information from the first enclosure controller via the second communication channel;

perform, using the master I/O module secured access information, first validation operations with the master I/O module via the third communication channel such that the first management service may securely access the single network management domain via the master I/O module; and

transmit the master I/O module secured access information to a second management service housed in the second chassis, wherein the master I/O module is configured to perform second validation operations with the second management service using the master I/O module secured access information such that the second management service may securely access the single network management domain via the master I/O module.

8. The IHS of claim 7 , wherein the first communication channel is provided via a secure hardware bus communication channel.

9. The IHS of claim 7 , wherein the second communication channel is provided via an Open Authorization (OAuth)-based secured communication channel.

10. The IHS of claim 7 , wherein the third communication channel is provided via a management Virtual Local Area Network (VLAN).

11. The IHS of claim 7 , wherein the first management service is configured to:

receive an announcement that was broadcast by the master I/O module and that includes master I/O module metadata; and

request, using the master I/O module metadata, the master I/O module secured access information from the enclosure controller.

12. The IHS of claim 7 , further comprising:

the first chassis that houses the first management module.

13. The IHS of claim 7 , wherein one of the at least one second I/O module housed in the second chassis is configured to transition to operate as the master I/O module in place of the at least one first I/O module.

14. A method for providing secure access to a network management domain, comprising:

retrieving, by a first enclosure controller via a first communication channel from a master I/O module that is included in at least one first I/O module that is included in a first chassis and that is configured to provide a single network management domain for a Multi-Chassis Management (MCM) group with at least one second I/O module housed in a second chassis that is included with the first chassis in the MCM group and that is part of a system management domain with the first chassis, master I/O module secured access information, wherein the system management domain is managed by one of a first computing system provided in the first chassis and a second computing system provided in the second chassis;
