I'm using a VPN script for Juniper's Secure Access protocol form here, which executes a binary located under ~/.juniper_networks/network_connect/ncsvc with the following permissions:

-rws--s--x 1 root root 1225424 okt.  25 13:54 ncsvc

But when I do, I get the following error:

ncsvc> Failed to setuid to root. Error 1: Operation not permitted

Moving/copying the ~/.juniper_networks folder to e.g. /opt/juniper (with the same owner permissions), I don't get the error. In the forum thread at Ubuntuforums someone pointed out that it's probably because I have encrypted my /home and thus a "problem" with ecryptfs.

How can I fix this?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
