Single sign on for external users for Communities

1) I have a customers maintained in a MySQL database
,2) The above data is used to authenticate and allow them to use one of our web application
3) We plan to create communities in Salesforce for Support Site
4) We want to use same user name for both Web Application and Communities with Single Sign On
I am newbie for Communities, can anybody provide highlevel provess to achieve this.
We are ready to make any changes required.

Hi Smallv,

There are many considerations here which you need to look at before you start on this. Do you currently manage your Community users and your web application users separately? Is your MySQL database your Identity provider or your Salesforce org going to be your Identity provider? If your Web application needs to be your IdP, have you configured an OpenSSO server which will allow you to use SAML Web server flow between Salesforce and MySQL? Do you have a third party IdP which you are planning to use for your Salesforce as well as MySQL instances? 

SSO is a complex topic and you will need to clearly define your requirements before starting implementing it.

Thanks
