New Installation, getting Access Denied with default login

[HCLMC]

I have a new installation, but using the default admin login tells me "invalid username or password" on both the UI and Identity projects. I've tried using both the username and email.

I can register a new user, and access the Identity project page, but I get access denied on the admin side.

I'm also confused because I've done the DB migrations, but when I register a new user it doesn't seem to be written to my database.

EDIT: Don't know how to delete the conversation, I found a DB connection reference I had missed. Updated that and everything works
