Now I am working on my local server to set up the GitLab as source control server.
For now every thing is working well：
The repositories are hosted in the server and can be accessed from my PC;
The LDAP authentication is ON and can be sign in the site via domain account perfectly.
The regular sign-in way is also ON for the invited users.
My GitLab version is 13.0.6-ee (4c8f8b0d9ee).
My question is: can we disable the regular sign-in and keep the LDAP auth only?
Thanks for taking the time to be thorough my question, any comments and suggestion will be really helpful and grateful . thank you very much.
