Domain (AD) Account Authentication Support for ServiceNow-NetBrain API Connector

NetBrain's ServiceNow connector currently authenticates only through a local NetBrain API account, with no option to use a Windows Active Directory (domain) account as the authentication source. This limits customers who are required to use centrally managed domain credentials for integration accounts rather than local application accounts. This enhancement would allow administrators to configure the ServiceNow-NetBrain connector to authenticate using a domain-based account, in addition to the existing local account option. Customers with security policies mandating domain-based service accounts would benefit from being able to meet compliance requirements while maintaining the ServiceNow integration.
