Keyword: User Profile Synchronization Service wont start


When configure user profile sync service, I get this error:

User Profile Application: SynchronizeMIIS encounters an exception: System.NullReferenceException: Object reference not set to an instance of an object.

This is because the FIM certificate has not been validated yet. The farm account which the sync service is running under must have access to Internet. This validation only needs to be done once, after the certificate is validated, you can disconnect Internet.

Error: "Not able to connect to search service to retrieve valid settings"

I tried to change the query of the search results webpart and I've got this:

Fix is to use the SharePoint management Shell and define your account as an SSA Admin.


Here's the code to add yourself as SSA admin:
$principal = New-SPClaimsPrincipal "<domain>\<user>" -IdentityType WindowsSamAccountName

$spapp = Get-SPEnterpriseSearchServiceApplication

$security = Get-SPServiceApplicationSecurity $spapp –Admin

Grant-SPObjectSecurity $security $principal "Full Control"

Set-SPServiceApplicationSecurity $spapp $security –Admin
