Sorry for my english

I have configure testlink and mantis with success to have a bug tracker system. A defect created on mantis and linked to a testlink failed test is well displayed.
But user must connect to mantis if he want to create a bug or see it (or connect with anonymous account).
Is there a plug-in to have linked management of user and projet between testlink/mantis ?
The existing interface between mantis and testlink is not usefull.
For example:
When we create a project under testlink, why not create automaticaly the same projet on mantis. The same thing for an user creation.
If user and project are the same between mantis/testlink, create a defect with testlink pop-up, on mantis would be easier ??
To resume, i would like to have an interface testlink/mantis like salome/mantis. It is possible ? it is existing ? it's in development ?
thank for your answer (if i'm not easy to understand i will make a picture to explain
