Hello,
I'm trying to implement SSO. I configured domain name and server, inserted admin username and password but it fails. I noticed in my DC this event:
Event Type: Failure Audit
Event Source: Security
Event Category: Account Logon
Event ID: 675
Date: 02/09/2010
Time: 12.05.00
User: NT AUTHORITY\SYSTEM
Computer: SERVER
Description:
Pre-authentication failed:
User Name: Administrator
User ID: DOMAIN\administrator
Service Name: krbtgt/DOMAIN.LOCAL
Pre-Authentication Type: 0x0
Failure Code: 0x19
Client Address: 192.168.***.*** (it is the astaro lan address)
The event 675 with failure code 0x19 is related to "Additional pre-authentication required" error. I have checked that the datetime of astaro and dc is the same. Does anyone suggest me a solution?
Notice that we currently use active directory in order to authenticate ssl vpn users in our ASG.
Other infos: from DC I can ping the ASG ip address but if I ping ASG host name ("asgfirewall") the name cannot be resolved. Could this be the cause of the issue?
