FAQs

Specific

Can the Security Pre-Trimmer be hosted on a separate server?

It is not recommended. There are content sources, such as Lotus Notes, that use Intersection ACLs, which requires that Group Expansion is executed in the same server where the content source is.


Reconfiguring the Security Pre-Trimmer

To reconfigure the Pre-Trimmer follow the next steps:

  1. Retrieve the current settings in the SharePoint Management Shell
 PS C:\> $ssa = Get-SPEnterpriseSearchServiceApplication
 PS C:\> Get-SPEnterpriseSearchSecurityTrimmer -SearchApplication $ssa
 
 
 SearchApp     : SearchServiceApplication Name=Search Service Application
 Id            : 1
 TypeName      : AspireSecurityTrimmer.AspireSecurityPreTrimmer, AspireSecurityTrimmer, Version=1.0.0.0,
                 Culture=neutral, PublicKeyToken=e87e053e181b45ec
 Properties    : ge~http://localhost:50505/groupExpansion~geTimeout~15000~claimIssuer~aspire~useDomain~false~
 IsPrePhase    : True
 CrawlRulePath : {0}{}

2. Remove the Security Pre-Trimmer using the Id from the previous step as Identity by running the following command:

Remove-SPEnterpriseSearchSecurityTrimmer -SearchApplication $ssa -Identity <id goes here>

3. Re-register the Security Pre-Trimmer with the necessary changes (i.e. increased timeout)

New-SPEnterpriseSearchSecurityTrimmer -Id 1 -TypeName "AspireSecurityTrimmer.AspireSecurityPreTrimmer, AspireSecurityTrimmer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e87e053e181b45ec" -SearchApplication $ssa -Properties "ge~http://localhost:50505/groupExpansion~geTimeout~2000~claimIssuer~aspire~useDomain~false~"


Restart the SharePoint Search Host Controller service (spsearchhostcontroller) now.
