Q: Profile Manager 3rd patry certificate gets overwriten

Hello, i have a Server in a Yosemite, Profile Manager was ok until one day that we have started getting issues enrolling devices. After check Server certificates we have detected that our godaddy certificate expiring in 1 month was replaced by another one expiring one year later after my last reboot. Every time we restore the keychain it appears again with the right and valid certificate but some time after it goes again to the strange one. At the Keychain system view i have 2 entries for this comercial certificate but no one is with the right date. At the login view i have the right certificate.

Now i need a solution to fix this. Any suggestions?

Thank You!
