Microsoft Flow – Add user to SharePoint Group

January 4, 2019 by Emad Gabriel

In Microsoft flow there is no built in action to add a user to a SharePoint group. One way to achieve this is to use the “Send HTTP request to SharePoint”

sendhttprequest

in this action you need to

  1. Set the URL of the Site
  2. Set method to “POST”
  3. URI set to “_api/web/sitegroups({GROUPID})/users”, example: _api/web/sitegroups(10)/users
  4. Add header with key=”accept” and value = “application/json;odata.metadata=none”
  5. Add header with key =”content-type” and value = “application/json”
  6. Set the Body to be {‘LoginName’:’i:0#.f|membership|[EMAIL ADDRESS]’}, example: {‘LoginName’:’i:0#.f|membership|john.doe@domain.onmicrosoft.com’}

It would look like this

sendhttprequest2

 

This is tested with a SharePoint online connection but assume might work with on premise SharePoint as well.

Error Installing SharePoint 2013 Prerequisites on Windows 2016 or 2012R2 (Error: The tool was unable to install Application Server Role, Web Server (IIS) Role)

September 19, 2018 by Emad Gabriel

When trying to install SP2013 on a windows 2012R2 or 2016 you may get the error : Error: The tool was unable to install Application Server Role, Web Server (IIS) Role

A quick fix might be to go to C:\Windows\System32\ , look for ServerManager.exe, make a copy and name it ServerManagerCMD.exe as this is the file that the SP prereqs is trying to call

IIS returns 404 error for an existing file

November 30, 2017 by Emad Gabriel

I had a case of an IIS site that had link to a local ODT file (Office Document Text, used by Open office and star office).

Anyone clicking on this link was getting a 404 error, file not found. I made sure the url is correct, the file exists where it is supposed to be, etc..

After some investigation, it turned out that this file did not have its MIME type defined in IIS. As a result IIS was not serving an unknown MIME type: https://support.microsoft.com/en-us/help/326965/iis-6-0-does-not-serve-unknown-mime-types 

To fix this issue, simply add the MIME type to the designated site

  1. Open IIS Manager and navigate to the level you want to manage. For information about opening IIS Manager, see Open IIS Manager (IIS 7). For information about navigating to locations in the UI, see Navigation in IIS Manager (IIS 7).
  2. In Features View, double-click MIME Types.
  3. In the Actions pane, click Add.
  4. In the Add MIME Type dialog box, type a file name extension in the File name extension text box. For example, type .xyz.
  5. Type a MIME type in the MIME type text box. For example, type application/octet-stream.
  6. Click OK.

PowerShell script to set URL redirects for SharePoint site using SPWebConfigModification

May 31, 2017 by Emad Gabriel

To have http redirects in a sharepoint we can use something like this in the web.config file

<location path=”oldpage1.htm”>
<system.webServer>
<httpRedirect enabled=”true” destination=”newpage1.html” exactDestination=”true” httpResponseStatus=”Permanent” />
</system.webServer>
</location>

One simple way of doing it using PowerShell is to use the SPWebConfigModication object.

The following script can achieve that

 

$Owner = “redirectMod”
$webApp = Get-SPWebApplication $Url

 

$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration”;
$modification.Name = “redirect-1” ;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “<location path='”+$from+”‘><system.webServer><httpRedirect enabled=’true’ destination='”+$to+”‘ exactDestination=’true’ httpResponseStatus=’Permanent’ /></system.webServer></location>”;
$webApp.WebConfigModifications.Add($modification);

$webApp.Update()
$webApp.Parent.ApplyWebConfigModifications()
do{
Start-Sleep -Seconds 2;
Write-Host “.” -NoNewline
$configJobRunning = IsWebConfigModificationJobPendingOrRunning $webApp;
}while ($configJobRunning);

Powershell to set URL Rewrite to SharePoint using SPWebConfigModifications

May 30, 2017 by Emad Gabriel

If we need to add some URL rewrite to a SharePoint site, we can do that using some web.config settings like :

<rewrite>
<rewriteMaps>
<rewriteMap name=”Redirects”>
<add key=”/Page1.html” value=”/Page1″ />
<add key=”/Page2.html” value=”/Page2″ />
</rewriteMap>
</rewriteMaps>
</rewrite>

One way to do that Is to use SharePoint Powershell commands.

The following script achieves that:
[Microsoft.SharePoint.Administration.SPWebConfigModification] $modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer”;
$modification.Name = “rewrite”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);

$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite”;
$modification.Name = “rewriteMaps”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);

$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite/rewriteMaps”;
$modification.Name = “rewriteMap”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);

$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite/rewriteMaps/rewriteMap”;
$modification.Name = “redirect-1”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);

$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite/rewriteMaps/rewriteMap”;
$modification.Name = “redirect-2”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);

$webApp.Update()
$webApp.Parent.ApplyWebConfigModifications()

do{
Start-Sleep -Seconds 2;
Write-Host “.” -NoNewline
$configJobRunning = IsWebConfigModificationJobPendingOrRunning $webApp;
}while ($configJobRunning);

SharePoint Site not accessible – 404 Page not found

April 11, 2017 by Emad Gabriel

One possible reason to have an error accessing a SharePoint site (page not found, 404 error) is that content database is not accessible by Pool user.

This could happen after restoring content database using SQL restore if you don’t follow the steps exactly.

In this case you will likely find in the ULS logs an error like

SqlError: ‘Cannot open database “WSS_Content_XYZ” requested by the login. The login failed.’

Quick fix: from central administration -> Manage content databases -> select the content database and check the “remove” to remove it from the farm and then add it again. when SP adds the content database back, it makes sure all required permissions are added and this could fix the problem.

SharePoint – Enable-SPFeature : The file is currently checked out or locked for editing by another user.

April 6, 2017 by Emad Gabriel

When running Enable-SPFeature, you may get the weird error:

“Enable-SPFeature : The file is currently checked out or locked for editing by another user.”

 

One possible cause of this issue could be that some file(s) the are deployed by the feature could be checked out by a user.

Checking the ULS logs you could find something like

 

Instantiating module “NAMEOFMODULE”: File could not be added at URL “FILENAME.jpg“: Error 689225296 99e77593-d0d4-49df-adcc-c8f8251fbb82

Published file is different between Authoring site and publishing site

April 4, 2017 by Emad Gabriel

We had a very weird issue today with a SharePoint publishing site. Some js and css files (which were deployed as part of a WSP) were not updated in the publishing zone.

When checking from the authoring zone, everything looked ok: the latest file was published and approved (was v1.0 since it was deployed as part of a solution). In the publishing site though, for end users, We were getting an older version of the file.

Tried clearing browser cache, close and open browser, use in-private browsing, resetting IIS, restarting server, restarting client machine, nothing worked.

After a lot of investigation and trials and errors, the issue turned out to be caused by the BlobCache. When we disabled the blob cache in the publishing zone, latest files started to work fine. With Blob Cache enabled, we were getting an older version.

For some reason even flush cache powershell command didnt seem to fix this issue. We had to disable the blobcache in the web.config for the publishing site and then manually delete the blob cache files. We then enabled blobcache again and things seemed to work fine.

More details about the nuts and bolts of BlobCache (long but interesting read) can be found at: https://sharepointinterface.com/2012/03/12/do-you-know-whats-going-to-happen-when-you-enable-the-sharepoint-blob-cache/
