Office 365 - ADFS Issue

[nelliott]

Hi All,

 

I am currently experiencing an issue with our ADFS access for Office 365, at present when using try to login they are redirected to our ADFS site, sts.lincolnutc.co.uk, however, it is reporting 503 – service unavailable errors.

 

I have connected to LUTCSQL1 which is the server which hosted the ADFS service and there are errors in the event log which started yesterday at 12:39:07 as seen below:

 

Until this evening, I thought the issue was related to the Microsoft issue reported in their Office 365 Admin portal, however, now this issue has been resolved by the MS team. Can anyone help?

When is your SSL certificates up for renewal?

Hi @jslate1980 where would I find out when it expires? ADFS is all new to me and was setup by someone else

Does it bring up any certificate errors when redirected from office365 to your adfs login page?

I'm assuming this is an ADFS proxy? You will need to get the certificate thumbprint from your ADFS server, then use the powershell cmdlet Install-WebApplicationProxy to re-establish trust between your ADFS server and Proxy.

Have a look here:
