Create CrmServiceClient for ADFS

Posted on by AndrewCampey

I've been reading the information I can find about Dynamics 365 and most of the examples show connections using a connection string.

Anyone know why this is?

Before I change to using Connection Strings has anyone connected to ADFS using CrmServiceClient and populating the variables? Something like the following

CrmServiceClient dynamicsService = new CrmServiceClient(new System.Net.NetworkCredential(Username, Password), AuthenticationType.IFD, Url, Port, Organisation, false, true, OrganizationDetail);

Fails for me every time.

RE: Create CrmServiceClient for ADFS

Andrew, not sure if you're still dealing with this since it's years later. But I had this issue stump me for the longest time, where I was using a connectionString in a config file with on-prem IFD using HomeRealmUri, and it wouldn't work. I eventually dug into Microsoft's Xrm.Tooling.Connector and found that if you set the AuthType to IFD, it IGNORES the HomeRealmUri parameter in your connection string. So HomeRealmUri only works if you manually specify it in the code in the CrmServiceClient constructor (though then the AuthType says it's "Claims"... but still seems to work).

Just thought I'd pass this along since I lost sooo much time to this issue

RE: Create CrmServiceClient for ADFS

Hi Scott,

What would be the connection string where the Azure AD is getting connected via ADFS and we are using Online d365?

Thanks

RE: Create CrmServiceClient for ADFS

Sorry for the delay! The following works but I can't get this to work using variables

string connect = @"AuthType = IFD; Url = <<URL>/<<OrgName>; HomeRealmUri=https://<<HomeRealm>/adfs/services/trust/mex/;Domain=<<Domain>; Username=<<User>@<<domain>; Password=<<Password>";

EDIT:- So the issue is the above allows me to include the home realm and set the Auth Type as IFD and it connects.

I can't seem to find somewhere to set HomeRealmUri and still use IFD. Am I missing something?

RE: Create CrmServiceClient for ADFS

What error do you get, and can you connect using other classes (e.g. OrganizationServiceProxy) ? If you can't, then the issue is likely to be with the ADFS configuration - there are scenarios where ADFS is incorrectly setup in a way that the UI client works, but programmatic access fails

RE: Create CrmServiceClient for ADFS

Hi Andrew,

I've done this lots of time yes! Have you tried adding the domain?

CrmServiceClient crmSvc = new CrmServiceClient(new System.Net.NetworkCredential("<UserName>", "<Password>", “<Domain>”), AuthenticationType.IFD, "<Server>", "<Port>", "<OrgName>", useUniqueInstance:false, useSsl:false, <orgDetail>);

Hope this helps!
