VMM: Failed to log on with the provided credentials

Postby guest » Wed May 20, 2009 8:23 am

Can't log into VMM 08 Self-Service Portal. Using domain admin credentials,
user is a member of the VMM 08 Administrators User Role.

This message is displayed on the login page:

"Failed to log on with the provided credentials. Make sure your user
name and domain are correct, then type your password again."

There are no errors in the system, security, or application logs at that
time. The IIS log shows a POST action with 200 reponse code:

2009-02-27 20:47:08 172.16.10.209 POST /Default.aspx - 80 -
172.16.10.209 Mozilla/4.0+
(compatible;+MSIE+7.0;+Windows+NT+6.0;+Win64;+x64;+.NET+CLR+2.0.50727;+SLCC1;+.NET+CLR+3.0.04506)
200 0 0 19157

Could use some pointers to troubleshoot this further, thanks,

Analysis:
1. One requirement to logon VMM Self Service portal is that the logon user
must be in "Self Service User Role".

2. I believe you must type correct password for the logon user, thus the
error could be the wrong password associated with the destination SPN for
this VMM service.

3. As the error is "wrong password", the most possible cause is the item #2
above.

According to this analysis, I would like to recommend the following action
to move forwards.

Suggestions:
1. Please ensure the startup account of VMM service are "Local System". If
it is domain account, please change it to "local system" and restart the
computer.
This is because the required SPN host\machinename is registered on
computer account, not domain user account.

2. If the step is not applicable, I still recommend you to configure this
logon user to be a member of "Self Service User Role" via

3. Please briefly go through all steps in
http://technet.microsoft.com/en-us/libr ... 17898.aspx and ensure there
is no any missed steps.

If this issue unfortunately persists, please follow the steps below to
collect information for our further investigation.

Action Plan:
1. Enable Kerberos Event Logging on the computer where you try to access
self service web portal.
=======================
(1) Start Registry Editor.
(2) Add the following registry value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Kerberos\Parameters
Registry Value: LogLevel
Value Type: REG_DWORD
Value Data: 0x1

If the Parameters subkey does not exist, create it.

(3) Restart the computer.

2. Double confirm the following audit policy enable on "default domain
policy" and "default domain controller policy" (if SCVMM server is a DC)
Account Logon Events - Failure
Logon Events - Failure
