Hi,

I am using EPiServer CMS 10.3.1 hosted on Azure Cloud. We have used IAM for authentication and autharization and then getting claim.

I am getting error "The parameter 'username' must not contain commas." for user while logging in.

[ArgumentException: The parameter 'username' must not contain commas.
Parameter name: username]
   System.Web.Providers.DefaultMembershipProvider.GetUser(String username, Boolean userIsOnline) +184

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +69

As users are stored from different system, how can I allow "," or "-" in the username, or is it not possible in Membership provider.

Please let me know if anyone knows solution, that will be a great help.

Thanks,

Can you use the user's email address instead for authenticating?

Hi,

I am not using it for authentication. I am using Identity access Management for User authentication. In my config file, there is

MultiplexingMembershipProvider is used. I guess, this is creating an issue. But what if I want to use Username for authetication, is that a problem.

Thanks & Regards,

Possibly depending on the provider. By default the Multiplexing provider uses Windows and Sql membership.

You could not use the older membership providers and go with AspNet Identity instead. This uses OWIN which you can configure to work with IAM.
