Omnibox Autocomplete asks for WIndows Authentication randomally

I have a omnibox autocomplete that sometimes popups the Windows Authentication popup. When I try to enter my credentials it still fails. It only happens in IE and to get it to replicate it I have to keep IE open for many minutes and try to type something in. I only need anonymous authentication for the searches. All the searches work just fine, just the autocomplete fails.

My config.yml looks like

  enabled: false
  provider: Active Directory

  enabled: true
  provider: Active Directory

  enabled: true
  name: S-1-1-0
  provider: Active Directory
  type: Group

The error message i get in the Search API log is

09:21:04.360 [qtp266272063-77] DEBUG c.c.s.a.i.SearchSessionFactory - Creating new local session with key:\FirstName.LastName,Sitecore Security Provider,User,None,None)!sortCriteria:occurrences,pattern:*Appointme*,field:@titlecomputed,errorsAsSuccess:1,patternType:Wildcards,maximumNumberOfValues:10,ignoreAccents:true,siteName:website,sitecoreItemUri:sitecore://web/{CE5B6A04-481E-43C0-88CE-53ACD78CF3FC}?lang=en&ver=1,queryOverride:

09:21:04.435 [qtp266272063-76] DEBUG - Bad credentials Bad credentials
    at ~[coveo-search-api-server.jar:na]

Did I configure something wrong? Did I miss something in IIS?

Hmm that's weird, I don't remember ever encountering something like this.

One thing to try: in windowsAuthentication section, add an entry like this one:

protocols: ["NTLM"]

This will for it to use NTLM instead of Kerberos. I'm curious to see if this helps.

Otherwise, if you don't need authentication at all for searches, you might also simply disable Windows Authentication altogether…
