How to authenticate users in MS Dynamics database with SharePoint

Hi,

I have this scenario where i need to authenticate some external with SharePoint. These users are stored in MS Dynamics database. After some searching, i found that there are two ways to implement it -

• Form Based Authentication with custom Membership providers.
• Custom Trusted Logins (SAML sign-in).

Any idea which would be a better option and how to implement it for MS Dynamics?

Thanks,

Thomas
