Where are the askbot settings saved? Unable to recover the settings

edit

Hi,

I am unable to login back to my local askbot instance.

I had initially configured admin login and enabled LDAP login.

I thought that now that LDAP login is enabled, I can disable local login and I disabled the option.

Now I am neither able to login with my admin account nor I am able to login with my ldap account.

Would it be possible to reset the setting from the settings file so that I am able to login back?

Thanks in advance
