VMware client – unable to login with username, password; but able to login with “use windows credentials”

We had this weird issue at work yesterday wherein you could not login to the vCenter server by entering a username/ password, but could if you just ticked on the “Use windows session credentials” checkbox.

The issue got resolved eventually by stopping the “VMware Secure Token Service”, restarting the “VMware VirtualCenter Server” service, and then starting the “VMware Secure Token Service”. No idea why that made a difference though, and whether that actually fixed things or was just coincidental. Around the same time I had seen some VMware Tools errors so I (a) upgraded the tools, (b) moved the vCenter VM to a different host, (c) saw that one of these had caused issues with the network driver so I had to uninstall and reinstall the tools and then reset the secure channel with the domain (since when the vCenter VM came up it didn’t have network connectivity).

So it was a bit of a damper actually. Nothing more frustrating than spending a lot of time troubleshooting something and not really figuring out what the issue is. On the plus side at least the issue got sorted, but it leaves me uneasy not knowing what really went wrong and whether it will re-occur.

In the event logs there were many entries like these:

An account failed to log on.

Subject:
    Security ID:        SYSTEM
    Account Name:        VCENTER01$
    Account Domain:        MYDOMAIN
    Logon ID:        0x3e7

Logon Type:            3

Account For Which Logon Failed:
    Security ID:        NULL SID
    Account Name:        SomeAccount
    Account Domain:        MYDOMAIN.COM

Failure Information:
    Failure Reason:        Unknown user name or bad password.
    Status:            0xc000006d
    Sub Status:        0xc0000064

Process Information:
    Caller Process ID:    0xe20
    Caller Process Name:    E:\Program Files\VMware\Infrastructure\VMware\CIS\vmware-sso\VMwareIdentityMgmtService.exe

Network Information:
    Workstation Name:    VCENTER01
    Source Network Address:    –
    Source Port:        –

Detailed Authentication Information:
    Logon Process:        Advapi  
    Authentication Package:    Negotiate
    Transited Services:    –
    Package Name (NTLM only):    –
    Key Length:        0

Here’s what the error codes mean –

  • NULL SID suggests that the account that was being authenticated could not be identified
  • 0xC000006D means that authentication failed due to bad credentials
  • 0xC0000064 means that the requested user name does not exist.
  • Logon type 3 means the request was received from the network (but given the request originated from “server”, suggests that the request was looped back from itself over the network stack.

Not that it throws much light on what’s happening.

For info – this KB article lists the useful vCenter log files. I looked at the vpxd-xxxx.log file which had some entries like these –

2016-06-06T16:08:18.046+01:00 [02856 error ‘[SSO]’ opID=138a737d] [UserDirectorySso] AcquireToken exception: class SsoClient::CommunicationException(No connection could be made because the target machine actively refused it)
2016-06-06T16:08:18.046+01:00 [02856 error ‘authvpxdUser’ opID=138a737d] Failed to authenticate user <mydomain\someaccount>

This file is under C:\ProgramData\VMware\VMware VirtualCenter\Logs by the way.

I also found messages like these –

2016-06-06T10:17:59.226+01:00 [06952 error ‘[SSO]’ opID=1790eabb] [UserDirectorySso] AcquireToken exception: class SsoClient::SsoException(Failed to parse Group Identity value: `\Authentication authority asserted identity’; domain or group missing)

Two more logs I looked at are C:\ProgramData\VMware\CIS\logs\vmware-sso\vmware-sts-idmd.log and some files under C:\ProgramData\VMware\CIS\runtime\VMwareSTS\logs. In case of the latter location I just sorted by the recently modified timestamp and found some logs to look at. I focused on one called ssoAdminServer.log. This file had a few entries like these –

[2016-06-06 12:19:08,987 pool-11-thread-1  ERROR com.vmware.identity.admin.server.ims.impl.PrincipalManagementImpl] Idm client exception
com.vmware.identity.idm.IDMException: Invalid group name format for [\Authentication authority asserted identity]

    at com.vmware.identity.idm.server.IdentityManager.findNestedParentGroupsInternal(IdentityManager.java:4006)

I found mention of this message in a forum post which pointed to this being a known issue for vCenter installed on a 2012 server with a 2012 DC. That doesn’t apply to me.

The vSphere Web Client gives an error message “Cannot Parse Group Information” – which too is a symptom if you install vCenter on a 2012 server with a 2012 DC. Moreover it applies to vCenter 5.5 GA, which is what we are on, so all the symptoms point to that issue but it is not so in our case. :(

Back to the vmware-sts-idmd.log, that had entries like these –

Again, something to do with DC/ domain … but what!? Found this blog post too that suggested the same.

For my reference, here’s a KB article listing all the SSO log files. And this is a useful blog post in case I happen upon a similar issue later (the case of the flapping VMware Secure Token Service). As is this KB article on an SSO facade error.
