[SharePoint 2010 – People Picker and SSO] Error solving “user does not exist or is not unique” on people picker, with single sign on solution

By

Error :

“user does not exist or is not unique”

Resolution : 

  • This error could come from a mapping with the user source that is not available (Active Directory, Single Sign On solution)
  • Try to reconnect the source

Context and detailed resolution : 

SharePoint + Ping federate (claim provider) for the authentication. The web application was configured to use ping federate. Then we did some configuration about sharepoint and ping federate by powershell (we added a new realm in ping and sharepoint), and the people people would show users from ping but issued, when we clicked on ok, by “user does not exist or is not unique”. 
=> As it was for a test environment, recreating the web application, seemed to refresh the custom claim provider and solved the problem.
In the next post i’ll give an global overview of a Claim provider, Single Sign on situation. From a sharepoint A, logged by Active directoy, we will be able to connect to a sharepoint B, by transfering the authentication. Transparent for the user and save him the time to relog on the SharePoint B environment.

If you call a method of image web service to retrieve pictures from a sharepoint user, you might get a 404 error because the picture references an old mysite collection, so the url is invalid.

To solution that problem, update every pictures of every users, you probably can do it by script powershell of console application.

[Windows 8] Passer de Windows Server 2008 à Windows 8

By
Jeff ANGAMA

Windows 8 est disponible pour le grand public dés octobre 2012 mais déjà disponible pour les étudiants grâce au programme MSDNA et Dreamspark premium. Ainsi je suis en train de migrer vers ce système d’exploitation.

Windows 8 Professionnel, orienté réellement professionnel

En développant Microsoft Windows 8, Microsoft a souhaité répondre aussi aux besoins des professionnels de l’informatique qui utilisent Windows Server 2008 comme OS pour leur tâches quotidiennes.

Je vais décrire ci-dessous, l’utilisation que je ferai de Windows 8 comme système d’exploitation avec Hyper-V afin de pouvoir l’utiliser de manière professionnelle.

Etat des lieux

J’utilise Windows Server 2008 comme système d’exploitation afin de pouvoir avoir Hyper-V. Cependant, cette solution s’accompagne de tout le bric-à-brac de Windows Server qui sont inutiles et encombrants.

 

Installation de Windows 8

En attendant d’être certain qui Win8 répondra à mon besoin, je l’ai installé sur une autre partition. L’installation prend environ 20minutes sur mon pc. Il ne me reste pus qu’à installer Hyper-V et les applications standards (Office, 7zip, Vlc…)

Pré-réquis pour installer hyper-v

Cet article décrit comment installer hyper-v sur windows 8

 

Utilisation de windows 8

A l’utilisation, windows 8 est très fluide. L’interface métro affiche une panoplie d’informations grâce aux applications provenant du windows store.

J’utilise souvent les touches Win + D afin de retrouver le bureau. ALT + Tab fonctionne toujours.

Il est toujours possible d’installer les applications qui fonctionnaient sous windows 7 ou windows server 2008.

Ainsi il est possible de travailler de la même manière que sous Windows Server 2008, sans le menu démarrer.

Je pense mettre un peu de temps à m’habituer à ne plus utiliser le menu démarrer, mais si le changement est trop dérangeant il est possible d’installer une des versions alternatives du menu démarrer grâce à des programmes tierces.

Professionnels de l’informatique ou non, quelles sont vos retours d’experience sous windows 8 ?

Tips for creating programmatically webpart, which class should you use (SP2010)

You want to create a webpart for SharePoint 2010 but you don’t know which class to use ?
I was using those way :

  • Search on google and find examples
  • Randomly type in Visual studio the webpart name, example : content, and it would propose me the classes ContentByQuery…

image
But there is a more simple way :

  • Create the webpart by interface in SharePoint 2010

image

  • Export the .webpart file from the webpartimage

This will export a .webpart

  • Now edit it with a text editor

image
You could see the full namespace used, and so the ClassName : ContentByQueryWebpart.

Hope that helped,

[SharePoint 2010 – Developpement] SPRunWithElevatedPriviledge still getting access denied

  1. Check that you ran the code inside sprunWithElevated
  2. Check that you re instantiate a spsite after using SPContext, otherwise the site object will be run with normal priviledge
  3. If you are using SPLimitWebPartManager (lien vers dispose objects), place it in the spRunWithElevated priviledge too, because it instantiate an instance of SPWeb !
