Support multiple domains for Azure SSO login

[bheemvennapureddy]

If the SubjectID for an existing login remains the same but the domain of the login changes, we want to support multiple domains during the transition to ensure a smoother user experience.

For example:

• Before: { subject: 1, login: abc@x.com }
• After: { subject: 1, login: abc@y.com }

This change involves updating only the domain (e.g., from @x.com to @y.com) while maintaining the same SubjectID.
