Hi, there
i follow instruction:
http://www.centova.com/en/faq/cast3/information/migrating_a_centova_cast_installation_to_another_server
step by step to migrate centovacast 3 to another server with CentOS 7.
after install centova cast work perfectly on new server. When import mysql database from old server give me this error
Unable to access account for 00: Cluster host authentication failure for Local server
when access user account or try to create new.

P.S i fix vhosts folder permision with /usr/local/centovacast/sbin/fixperms

why?

I believe you need to go to /usr/local/centovacast/etc/rpcshadow copy that password log into the admin
under management click hosts click the gear button the edit the host where it says authentication key paste the key from /usr/local/centovacast/etc/rpcshadow into the box hit save and you should be fine.
