Cisco AnyConnect Secure Mobility Client on OS X Yosemite - CSD library signature verification failed

[a1exus]

I just updated my MacBook Pro (Retina, 15-inch, Early 2013) to latest OS X Yosemite (10.10 (14A389)). Cisco AnyConnect Secure Mobility Client is generating an error while trying to connect:

Posture Assessment Failed: CSD library signature verification failed.

Cisco AnyConnect Secure Mobility Client VPN User Messages, Release 3.1 - Cisco states following:

CSD library signature verification failed.
Description    The signature of the library could not be verified. This indicates a problem with the CSD library.

Recommended Action    Remove the library from the cache, and try a new connection.

I tried recommended action yet it did not help me solve my issue, as I'm still unable to connect to VPN.

Do you have AnyConnect 3.1.05187? That's the first version to support OS X 10.10.

I'm using latest version that is available for download through Cisco's site which is 3.1.05187, and still unable to connect!

We're seeing the same error with that client, were you able to find a fix?  thanks.

We removed CSD from the configuration and used the latest version of HostScan instead:

no csd image disk0:/csd_3.5.841-k9.pkg
csd hostscan image disk0: /anyconnect-win-3.1.05187-k9.pkg
 

hostscan has to be on version 3.1, same as client in order for this to work! as soon as we updated our hostscan to 3.1+, i was able to vpn in without any issues)
