Lack of interaction between Poulpe Auth Plugin in Preprod and Poulpe

We don't get any changes when we make some manipulation with groups in Poulpe.

Steps for reproduce:
Test scenario #1:
1. You should have registered user as User1. Go to Poulpe and add him in 'Banned users' group.
2. Go to Preprod and loggin as User1.
3. Go to PM and try to sent message to some existing user.

AR: User can sent message
ER: User shouldn't have ability to create PM and see 'Compose' button

Test scenario #2:
1. You should have registered user as User1. Go to Poulpe and add him in 'Administrators' group.
2. Go to Preprod and loggin as User1.

AR: User logged as ordinary user without extended permissions
ER: User should have access to 'Administration mode'

Note In QA instance plugin works correctly
