SYMPTOMS
When GetUserNameEx is used to make an SSL call to a Microsoft Internet Information Server-based server, you may receive a 1212 error code that is translated to:
When an ADSGetObject Active Directory Service call is made, it may generate the following 0x80005000 error:
CAUSE
AdsGetObject does not work because of delegation. The call goes as anonymous during communication to the domain controller (DC). Because of this, during the search for a Fully Qualified Domain Name (FQDN), the server returned success with no entries.
The client uses schannel certificate mapping to authenticate to the server that is running Internet Information Server (IIS). Schannel builds a token that cannot be delegated on the IIS server (SSL/TLS is a non-delegatable protocol), and schannel uses pass through and sends only certificates and names.
The IIS server impersonates the client token, and makes an ADSI call to the DC. Negotiation routes to NTLM because no Kerberos credentials exist, and NTLM drops to anonymous because no primary credentials exist.

WORKAROUND
To try to work around this problem, use any of the following methods.
- Use RevertToSelf before you make the call to the DC, restore the original token after the call, and then run IIS under a domain user account that has access to the objects in question.
- Adjust the ACLs on the appropriate objects to grant everyone the minimum-needed access (read).
- Run IIS on the DC. This works because it effectively avoids the second authentication process.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.
