As a follow-up on this post :
Set the application security on the Connections applications, my colleague John adapted the configuration file for Connections 4.5:

You can download it here , and change at your leisure : appsecurity.connections45.txt

Update: I fixed a few issues with the original script , so get your new version here : setApplicationSecurity2.py

To execute , start wsadmin on the Dmgr like this :

./wsadmin.sh -f /path-to/[setApplicationSecurity2.py](/assets/files/jython/setApplicationSecurity2.py "setApplicationSecurity2.py")  -lang jython -username (your wasadmin user) -password (your password) /path-to/[appsecurity.connections45.txt](/assets/files/jython/appsecurity.connections45.txt "appsecurity.connections45.txt")
