my domain changed - can't access vault

[ptansey]

Our network operations team is in the process of migrating our domain users to a new domain.
I was on domain abc.com, but my account is now def.com

When I try to launch the vault client or website and login as either old or new domain accounts, I'm told my username or password is invalid.
I fear I was the only admin user on that server.
Is there anything I can do?

Were you using Active Directory logins? If so, then someone needs to login to the Vault admin web page with the admin login (name: admin, password: set by person installing) and add the new domain name to the list of domains Vault can check. Then users should have their logins set to go to the appropriate domain or set to check all domains.
