i created new user into my ESXi 6.5 host.
roles and permission assigned, but i still cannot login.
error message is Cannot complete due to incorrect user name or password.
have already followed the recommended steps to create new users and assigned roles through the web gui
Do you have access via root user?
Error clearly stats about incorrect username and password. Please ensure usernama and password are case sensetive so be careful in that.
Reset the password.
