# Use of Office365 authentication with the WS-Trust security protocol
20+
21+
Use of the WS-Trust authentication security protocol when connecting to Common
22+
Data Service is no longer recommended and has been
23+
deprecated; see the [announcement](/power-platform/important-changes-coming#deprecation-of-office365-authentication-type-and-organizationserviceproxy-class-for-connecting-to-common-data-service).
24+
25+
This change
26+
impacts custom client applications that use “Office365” authentication and the
27+
[Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy](/dotnet/api/microsoft.xrm.sdk.client.organizationserviceproxy)
28+
or
29+
[Microsoft.Xrm.Tooling.Connector.CrmServiceClient](/dotnet/api/microsoft.xrm.tooling.connector.crmserviceclient)
30+
classes. If your applications use this type of authentication protocol and API,
31+
continue reading below to learn more about the recommended authentication
32+
changes to be made to your application’s code.
33+
34+
## How do I know if my code or application is using WS-Trust?
35+
36+
First and most importantly, this change **only** impacts client applications that
37+
connect to the Common Data Service. It does not impact custom plug-ins,
38+
workflow activities, or on-premises/IFD service connections.
39+
40+
- If your code employs user account and password credentials for authentication with Common Data Service or an application, you are likely using the WS-Trust security protocol. Some examples are shown below, though this list is not fully inclusive.
41+
42+
- When using the [CrmServiceClient](/dotnet/api/microsoft.xrm.tooling.connector.crmserviceclient) class with a connection string:
43+
44+
`connectionString="AuthType=Office365; Username=jsmith\@contoso.onmicrosoft.com;Password=passcode;Url=https://contoso.crm.dynamics.com"`
45+
46+
- When using [OrganizationServiceProxy](/dotnet/api/microsoft.xrm.sdk.client.organizationserviceproxy) class constructors:
47+
48+
49+
```csharp
50+
using (OrganizationServiceProxy organizationServiceProxy =
51+
new OrganizationServiceProxy(serviceManagement, clientCredentials)
52+
{ ... }
53+
```
54+
55+
- If you are using the `OrganizationServiceProxy` class at all in your code, you are using WS-Trust.
56+
57+
- If you are using [CrmServiceClient](/dotnet/api/microsoft.xrm.tooling.connector.crmserviceclient).`OrganizationServiceProxy` in your code, you are using WS-Trust.
58+
59+
## What should I do to fix my application code if affected?
60+
61+
There are very straight forward ways to modify your applications code to use
62+
the recommended connection interface for authentication with Common Data
63+
Service.
64+
65+
- If your code uses an [Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy](/dotnet/api/microsoft.xrm.sdk.client.organizationserviceproxy) instance:
66+
67+
If you are passing the `OrganizationServiceProxy` instance around to various methods, or returning the instance from a function, replace all occurrences of the type `OrganizationServiceProxy` with the [IOrganizationService](/dotnet/api/microsoft.xrm.sdk.iorganizationservice?view=dynamics-general-ce-9) interface. This interface exposes all the core methods used to communicate with Common Data Service.
68+
69+
When invoking the constructor, it is recommend you add the NuGet package [Microsoft.CrmSdk.XrmTooling.CoreAssembly](https://www.nuget.org/packages/Microsoft.CrmSdk.XrmTooling.CoreAssembly/) to your project and replace all use of `OrganizationServiceProxy` class constructors with [CrmServiceClient](/dotnet/api/microsoft.xrm.tooling.connector.crmserviceclient) class constructors. You will need to alter your coding pattern here, however, for simplicity `CrmServiceClient` supports connection strings in addition to complex constructors and the ability to provide external authentication handlers. `CrmServiceClient` implements `IOrganizationService`, therefore your new authentication code will be portable to the rest of your application code. You can find examples on the use of `CrmServiceClient` in the [PowerApps-Samples](https://github.com/microsoft/PowerApps-Samples/tree/master/cds/orgsvc/C%23) repository.
70+
71+
- If your code is using [CrmServiceClient](/dotnet/api/microsoft.xrm.tooling.connector.crmserviceclient) with theOffice365authentication
72+
type:
73+
74+
An example of this is a connections string that looks like this:
75+
76+
`connectionString = "AuthType=Office365;Username=jsmith@contoso.onmicrosoft.com;Password=passcode;Url=https://contoso.crm.dynamics.com"`
77+
78+
Similarly, you could also use a `CrmServiceClient` constructor and pass in `AuthType.Office365`.
79+
80+
You have two options for dealing with this.<p/>
81+
82+
- Switch over to using an OAuth based connection string. Such connection string looks like this:
83+
84+
`connectionString = "AuthType=OAuth;Username=jsmith@contoso.onmicrosoft.com;
85+
Password=passcode;Url=https://contosotest.crm.dynamics.com;AppId=51f81489-12ee-4a9e-aaae-a2591f45987d;
86+
RedirectUri=app://58145B91-0C36-4500-8554-080854F2AC97;LoginPrompt=Auto"`
87+
88+
This will be your fastest way to update the code. Note that LoginPrompt can be set toneverto simulate the way that the Office 365 behavior worked.
89+
90+
The AppId and RedirectUri provided above are examples of working application registration values. These values work everywhere our online services are deployed. However, they are provided here as examples and you are encouraged to create your own application registration in Azure Active Directory (AAD) for applications running in your tenant.<p/>
91+
92+
- When we announce it, update to the latest [Microsoft.CrmSdk.XrmTooling.CoreAssembly](https://www.nuget.org/packages/Microsoft.CrmSdk.XrmTooling.CoreAssembly/) NuGet package that includes auto redirect support. This library will redirect an authentication type of Office365 to OAuth and use the example AppId and Redirect URI automatically. This capability is planned for the 9.2.x version of the Microsoft.CrmSdk.XrmTooling.CoreAssembly package.
93+
94+
- If you are accessing the [CrmServiceClient](/dotnet/api/microsoft.xrm.tooling.connector.crmserviceclient).`OrganizationServiceProxy` property:
95+
96+
Remove all use of that property in your code. `CrmServiceClient` implements `IOrganizationService` and exposes everything that is settable for the organization service proxy.
97+
98+
> [!IMPORTANT]
99+
> Regarding not being able to login using User ID/Password even if using OAuth: if your tenant and user is configured in Azure Active Directory for conditional access and/or Multi-Factor Authentication is required, you will not be able to use user ID/password flows in a non-interactive form at all. For those situations, you must use a Service Principal user to authenticate with Common Data Service.<p/>
100+
To do this, you must first register the application user (Service Principal) in Azure Active Directory. You can find out how to do this [here](https://docs.microsoft.com/azure/active-directory/develop/howto-create-service-principal-portal). During application registration you will need to create that user in Common Data Service and grant permissions. Those permissions can either be granted directly or indirectly by adding the application user to a team which has been granted permissions in Common Data Service. You can find more information on how to set up an application user to authenticate with Common Data Service [here](/powerapps/developer/common-data-service/use-single-tenant-server-server-authentication).

### About the reparent action
6368
The reparent action is very similar to the share action except that it deals with the inherited read access rights instead of explicit read access rights. The reparent action is when you change the value of the referencing attribute in a parental relationship. When a reparent action occurs, the desired scope of the inherited read access rights for related entities might change. The cascade actions related to the reparent action refer to changes to read access rights for the entity record and any entity records related to it.

### Parental entity relationships
107112
Each pair of entities that are eligible to have a 1:N relationship can have multiple 1:N relationships between them. Yet usually only one of those relationships can be considered a parental entity relationship.
