-Log in to SQL Server where we have CRM databases <org>_MSCRM and MSCRM_CONFIG. We have 4 different tables from where we will have to fetch the user entries.

 

-SystemUserBase,

-SystemUserOrganizations,

-SystemUser and then

-Organization

 

Refer to the following diagram which will help you understand how different tables are related for a specific user.

 

 

 

 

 

Run following queries one by one and fetch the GUID values as follows:-

 

Run below query on ORG_MSCRM database :-

 

Select domainname,systemuserid from systemuserbase where domainname ='domainname\username'

 

Note:-

domainname\username is for the affected user.

 

Copy SystemUserID = 7F0F58A8-5ED0-E111-B576-00155D5AC438

 

 

 

 

Run following query in MSCRM_CONFIG database :-

 

USE [MSCRM_CONFIG]

select UserId from systemuserorganizations where CrmUserId='7F0F58A8-5ED0-E111-B576-00155D5AC438'

 

Copy UserId = D058E3E4-EF63-E111-97DA-00155D5AC42A

 

 

 

  USE [MSCRM_CONFIG]

select defaultOrganizationId from SystemUser where id='D058E3E4-EF63-E111-97DA-00155D5AC42A'

 

Copy default org id= 076DC913-4564-4569-9A8C-9CD1C4A4ABA2

 

  

 

USE [MSCRM_CONFIG]

select DatabaseName,UniqueName from organization where id = '076DC913-4564-4569-9A8C-9CD1C4A4ABA2'

 

 

Default Org XXX_MSCRM

 

This way we can find the default organization for any user.
