Organizations are stored in MSCRM_CONFIG.dbo.Organization

Tables in MSCRM_CONFIG

SystemUserRoles	Has an entry for each users that is currently a deployment administrator. Links to the SecurityRole table with SecurityRoleId
SystemUserAuthentication	Any user that has been added to any organization in the deployment.
SystemUserOrganizations	Has an entry for each user/organization combination. Users are referenced by UserId (in SystemUserAuthentication) and CRMUserId (in each org db?)

SystemUser table

Column	Notes
DefaultOrganizationId	The value is 00000000-0000-0000-0000-000000000000 for users that are deployment administrators
Id	Unique identifier for the table

SystemUserAuthentication table

Column	Notes

Use wmic useraccount get name, sid at the command prompt to retrieve SIDs

Tables in Org_MSCRM
