Error Cmbi0132 Password Is Incorrect Please Try Again

ارسال یک نظر

Hello community, I am new here but have been lurking around - until now there hasn't been a problem I couldn't solve by looking on the internet & these forums or by myself.. I have reached the stage where I tried everything I could and the internet can't provide more results about the problem for me so I'm opening a new question, I really hope we can get this fixed together and I appreciate ur help <3

alright so, tl;dr - I started to work in a company as a Sysadmin and the last guy that I replaced really messed some stuff around and I'm spinning around trying to fix them..

I'm going to try to sum up everything in one post to avoid being asked the same questions over and over again.

The Problem:

I cannot access ECP/OWA, no matter which credentials I give it (and they are validated as correct vs Outlook itself) - Outlook works, ECP/OWA does not.

The error I get, no matter where I access it from (Internally / Locally) -

"The user name or password you entered isn't correct. Try entering it again."


- I think the problem relies within owa (Exchange Back End) / ecp (Exchange Back End), as I tried various solution suggestions I may have deleted the back end Virtual Directory to recreate them.

Some Info:

OS and Exchange: Windows Server 2016, Exchange 2016

Exchange CU Version: CU6

Logs & Debugging:

Event Viewer:

Text

                The Outlook Web App configuration settings couldn't be read and updated. Virtual directory: "owa". Web site: "Exchange Back End". Error message: "The Active Directory configuration settings couldn't be accessed for virtual directory "owa" under Web site "Exchange Back End"."  -> Source: MSExchangeOWA -> Event ID: 64 --> Qualifiers: 49152

IIS:

W3SVC1 (Default Web Site?) + W3SVC2 (Exchange Back End?) log files don't say much actually , no indication of errors when I try to login. Here's a few lines I found (but its about health mail boxes);

ADSI vs IIS:

You can see that there is no "owa (Exchange Back End) / ecp (Exchange Back End)", that might be the problem.. didn't have time to compare these vs my local hosted mail server to confirm.


This is in:

Text

                CN=HTTP,CN=Protocols,CN=Mail_Server,CN=Servers,CN=Exchange Administrative Group (GUID_HERE),CN=Administrative Groups,CN=DOMAIN_NAME,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=DOMAIN_NAME,DC=local

IIS:

* Default Web Site


* Exchange Back End

I think it'll be important to mind that I've had a lot of problems before that and they have been fixed and that one popped up (probably my mistake) recently after solving a lot of errors that came before that about OWA.

Believe me I dug every hole in the internet to find a solution without success, I have a final solution planned (as a Plan B at the moment) which is upgrading Exchange from CU6 to CU10 (planned to happen soon) but I can't really do that at the moment, keeping in mind that those are production servers and I cannot do whatever I want.

Tried solutions:

  1. Recreating virtual directories (including webApplications) & Recycling AppPools (OWA & ECP)
  2. Changing authentication methods and SSL settings back to default (https://docs.microsoft.com/en-us/exchange/clients/default-virtual-directory-settings) + comparing to a local mail server hosted at home.
  3. Checking permissions (permissions are fine)
  4. Checking Bindings and SSL cert attached to https bindings
  5. Comparing IIS config files found at C:\Windows\System32\inetsrv\config\ vs My local hosted Mail Server (didn't really find much difference)
  6. Restarting IIS ofcourse (tons of times) and Rebooting
  7. Analyzing with Exchange Analyzer (https://gallery.technet.microsoft.com/office/Exchange-Analyzer-6e20132e) - no critical errors or anything noticeable relating ECP / OWA / Webservices
  8. Updating CAS (C:\Program Files\Microsoft\Exchange Server\V15\Bin\UpdateCas.ps1)
  9. Testing Exchange connectivity (https://testconnectivity.microsoft.com/) - No errors whatsoever
  10. More (can't remember anymore.. too much)

I hope all of this helps analyzing the problem and fixing it , hope we can find a fix for this without having to upgrading exchange / reinstalling and thanks for reading

Update: following https://dirteam.com/dave/2010/12/23/fixing-a-broken-owa-2010-virtual-directory/ I might have fixed the constant errors @ Event Viewer

But I still cannot log-in! Will follow logs and Event Viewer to make sure and update later.

Update #2 : I have found a solution and now owa & ecp both are fully working!

Here's what I did:

SOLUTION:

I have had no errors anymore, not in the Event Viewer or IIS logs so, I have been thinking to myself that maybe the same way I have been doing in https://dirteam.com/dave/2010/12/23/fixing-a-broken-owa-2010-virtual-directory/ to fix the ADSI Object of ECP and OWA That I would do the same concept but instead of comparing between ADSI's, this time maybe Comparing between an example machine's working ECP/OWA config files and a broken ECP/OWA config files may reveal the problem to me!

So I fired up my local Exchange 2022 server back at home and compared 3 Files using https://www.diffchecker.com/ to check what is wrong.

I have gone ahead and compared between those 3 web.config files located at:

Text

                [Exchange_Install_Drive]\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\ecp [Exchange_Install_Drive]\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\owaC:\inetpub\wwwroot

To my surprise I have found some wrong parameters and empty parameters in those files , so I went ahead and made a backup for those files and carefully removed those parameters, saved those files and restarted the IIS service (iisreset)

ECP and OWA are now fully working for me!

Thanks everyone for helping and I hope this will help everyone having those kind of problems in the future.
