Hey guys. I am creating a site that needs to integrate with Dynamics CRM. The site's final users must be in CRM, so I need to create a custom membership provider. All is good till now, the custom membership provider workds ok, authenticating users as expected against CRM.

The problem arroused whrn trying to log in to the Umbraco backend. For some strange reason, my Membership provider is getting called from the Umbraco backend login window. If I comment out the custom provider, then I can log into the Umbraco Backend, but every time the custom provider is present in web.config, then my routines get fired.

I tried to inherit the custom membership provider both from System.Web.Security.MembershipProvider AND from Umbraco.Web.Security.Providers.MembersMembershipProvider, with the same result. So the only way to access Umbraco Backend is to comment out the custom membership provider in web.config.

Here is a excerpt from web.config with the providers:

<membership defaultProvider="UsersMembershipProvider" userIsOnlineTimeWindow="15">

<providers>

<clear />

<add name="XrmMembershipProvider" type="xmsbs.providers.bllXrmMembership" enablePasswordRetrieval="true" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="XMS Extranet" />

<add name="UmbracoMembershipProvider" type="Umbraco.Web.Security.Providers.MembersMembershipProvider, Umbraco" minRequiredNonalphanumericCharacters="0" minRequiredPasswordLength="4" useLegacyEncoding="false" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" defaultMemberTypeAlias="Member" passwordFormat="Hashed" />

<add name="UsersMembershipProvider" type="Umbraco.Web.Security.Providers.UsersMembershipProvider, Umbraco" minRequiredNonalphanumericCharacters="0" minRequiredPasswordLength="4" useLegacyEncoding="false" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" passwordFormat="Hashed" />

</providers>

</membership>

Any guidance on how to solve this problem will be greatly appreciated.

Best regards, Ariel
