This error happens when you use a Windows authentication user to log on to ePO and try to register
NSX-T.
In Windows authentication, users can be assigned either dynamically or manually. If a user is assigned dynamically, the username is in the format of
domain name\user. For example, the username of the user logged into ePO is
trellix\rgc.
Here, MOVE doesn't understand this syntax (domain name followed by a back slash) when connecting to
NSX-T for registration.
The
VMware API for
serviceinsertion doesn't properly handle the "
\" character in the
domain name\user of the ePO account used within this API for
NSX-T registration. The character is treated similar to the escape character instead of a string value.
