[5.2]Oauth JSON answer bad formatted

[Florent Thomas]

Hi,

I've installed successfully 5.2 from graddle overlay and plug it to our LDAP server. I've registered multiple services and succeed to login, redirect etc...
For some service I have no problem because the answer is not parsed.

So globally the process works except that I have answers not well formatted :
Here is an example of what I get as an answer : https://github.com/OCA/OCB/pull/692#issue-288451637
Is there any way to deal with a conf that produce a result like this one : {"p": 4, "r": "http://localhost:8069/web", "d": "mag_prod10_2018_01_12"}

Thanks in advance
