Connect two Social Accounts suign Django Allauth

[Deshraj Yadav]

I am working on a Django Project and I am using django allauth. I am facing a problem described below:

So the current usecase is :
First a user signs with an email-Id: ab...@xyz.com through his google account. Then he is assigned username: abcd . After he logs out and then when he logs in through Dropbox with the same email id , then a new entry is created in social_accounts table with username: abcd2. Why so ? Is it possible to connect these two accounts and have a single user entry ?

(Note: The user has not yet registered through simple login method.)
