[SOLVED] automatic user rights assigment following contract (or project) validity

Dear community,

I would like to know if it would be anyhow possible :
- to allow the users who are contacts for a customer to create ticket only if a given contract (or project) with this customer is still open (and to disable ticketing from the users if the contract is closed).
OR
- to set automatically the users who are contacts for a customer as closed if a given contract with this customer is closed.

Many thanks for your input !

I understand it is not possible as such, but I can create a project corresponding to the contract and close it when the contract is finished. At least it closes all the connected account linked in a go (if numerous).
I might use this, and create a project per product and a sub-project per contract.
Automation would be an interesting future feature though.

Many thanks !
