When you try to log in to a virtual machine through Power Panel with valid credentials, you get the following error:
An invalid username or password. Please try again.
Similar errors are observed in the Power Panel log:
# tail -f /var/log/pva/pp/2014.06.20-cpcon.log 20/06/2014 19:17:38.8194580  : virtual AuthResult<unnamed>::SsoVEuserAuth::log_on(WebCP*, const HttpRequest&, const VZL::VZLGUID&, const VZL::eid_t&, Session**) at AuthMethods/SsoVEuserAuth.cpp:118 : (SSO) No SAML token in request - user is not authenticated.
Direct login via command line also fails:
# prlctl auth VMNAME --username root --userpassword PASSWORD Authenticating user with VM security database... Failed to authenticate user with VM security database: Unable to authenticate the user. Make sure that the specified credentials are correct and try again.
You know that the credentials are valid because you are able to log in to the virtual machine with these credentials by SSH/RDP.
The virtual machine is not using an emulated HDD and has a real drive passed to it:
# prlctl list -i RS000003 | grep hdd Boot order: net0 hdd0 hdd0 (+) sata:0 real='LOGICAL VOLUME HP (/dev/sdc)'
The issue is recognized as a product bug with internal ID PSBM-27642.
The fix is included in Parallels Cloud Server 6.0 update 7.
