OMV7 Fresh install on RPi 5 8GB - default admin user and password not working.

[Coxis]

Describe the bug

I installed OMV7 onto a RPi5 8GB using the guide here:

https://wiki.omv-extras.org/doku.php?id=omv6:raspberry_pi_install

Everything went swimmingly until OMV7 finished installing. I opened the GUI, and despite what the guide says, the default username of admin and password of openmediavault are not working. I'm not copy pasting, I'm typing manually and being careful that there aren't any leading or trailing spaces. When I burned the RPI OS Lite 64bit image onto the SD card, the username I added for ssh access was NOT named admin. It was named something completely different... like billy, for example. It wasn't pi either. Does it have to be pi?

I can no longer ssh into the pi using the username "billy" I created during SD card imaging. I assume this is the expected behavior.

I can actually log into the GUI using that same "billy" user I set up during SD card imaging, but I can't do anything, there's only buttons to log out and change language, nothing else. I assume due to lack of privileges.
