Removing federated SSO login redirect from 365
I made the mistake of trying to set up SSO through Lastpass on our Microsoft tenant this morning. I messed up the Lastpass side and in the middle of the whole thing, my system blue screened so that I lost my persistent connection to Power Shell I had used this command in it to set up the authentication to Lastpass with all the variables they specified:
Set-MsolDomainAuthentication -FederationBrandName $domain -DomainName $domain -Authentication federated -PreferredAuthenticationProtocol SAMLP -IssuerUri $issuer -SigningCertificate $certificate -PassiveLogOnUri $ssoUrl -ActiveLogOnUri $ecpUrl -LogOffUri $logoffUrl -Verbose
What the article I was following didn't tell me is that it would force all authentication to the portal now to go through LastPass:
So, now when I go to https://portal.office.com and put in ANY username for the tenant, I get redirected to LastPass when the application doesn't exist anymore with the settings I specified. I am in a full panic now. I opened a ticket through another tenant to get Microsoft's help, but they are behind and I don't know when they will call me. What can I do? Is there a way to bypass this? Even trying to authenticate in Power Shell brings me to the LastPass login like a giant loop.
If someone can help me that works at Microsoft, I can verify any info about the tenant. The one in question is arcemsolutionsllc.onmicrosoft.com and my login is chad@Eric George .com. I am a global admin for it.
Do you have any other global admin account with .onmicrosoft.com in the UPN suffix?
Sure do. Just like mine, they all redirect to the SSO login that doesn't work.
