Failed to start Authorization Manager

[Taryck]

Hi Experts,

I've got a emergency. When I reboot, I no longer got SSH and Consol screen (on local display) display an error message : "user not know underlying authentification module".

Why did I reboot :

1. I wasn't abled to start new ssh session error : ssh_exchange_identification: read: Connection reset by peer
2. When I look to my directories (with ll) I've got 0 as owner instead of root

I thought that a reboot my solve both theese issues but I doesn't.

I've tryed to :

• reboot as normal default menu entry
• reboot on previous kernel version
• reboot with debuging... which leads to the following screen.

The first error showned is Failed to start Authorization Manager

But does any one has suggestion for the root cause ? And how to fix that ?
To get back ssh access ?

If it's showing 0 instead of 'root' then that sounds like either it's unable to read /etc/passwd or someone has removed the line for root inside that file.

Did you attempt to change your root password from an emergency boot?
