Hello!
I changed my admin user name and password, as the doc says, but I'm unable to login again on my instance (using AWS).
I reset the password with
sudo htpasswd -cbm /usr/local/coronium/conf/admin_auth admin coroniumserver
And then, I has been able to login.
After some testing, I found that the problem may be on using symbols as # $ % &, ... on the password.
Finally, I used a password without symbols to avoid problems, but I think any password field must admit (at least some) symbols.
So... may I suggest to add to your long TODO list looking at this and solving by one of this options, for example:
a) allow symbols
b) doc about allowed (or unallowed) symbols
Thank you!!
