Sign In GitHub Enterprise via LDAP fails due to change username

Question

My company hosts a github internal site using LDAP to authenticate, and uses the company's database as login credentials. Everything works fine until I change the username of the account through the link:

git.xxx.com/account/rename_box

Then I change the username, and I am still able to view the github page through:

git.xxx.com/newusername

However, now I can't log in via LDAP, it shows invalid login and remind me that my company email account has been taken

So what can I do? Is sending email to the administrator to change and reconfigure the username the only solution or I can change the odds by myself through some ways?

Answer 1

Solved this problem by contacting the git admin by reverting the username back to the original
