Using kerberos ticket on web browsers

Diego,

It is not possible to configure IE to use anything other than LSA for getting credentials, however Firefox can be configure to use a GSS-API library, so you can configure Firefox to use the MIT gss dll and then it can access credentials obtained by your GINA.

To find out how to configure Firefox, look in help or let me know if you get stuck.

Thanks,
Tim

Hello again,

We don't have any windows AD server on the network (actually, we have no 
Windows servers, AD or not). Currently we get our tickets from a Debian 
server configured with a Samba+OpenLDAP+MIT Kerberos. While windows doesn't 
get a ticket at logon, we use a combination of MIT for Windows and a custom 
GINA to acquire the tickets from our Kerberos KDC.

These tickets are stored in two places: a file on a network share and the 
MIT API krb5cc; We have no tickets in the LSA, which (I believe) is where IE 
and Firefox are trying to get the tickets from, and we need to point them 
towards either ticket location (file or API).

Thank you,
