Unable to set Admin users password to access webadmin Portal of RHEV Manager

Issue

• I get the following error while trying to set the password according to the man-page:

# engine-config -a | grep -i Password
LocalAdminPassword: Failed to decrypt the current value.
SysPrepDefaultPassword: Empty version: general
AdminPassword: Failed to decrypt the current value.

# engine-config -s PasswordEntry=interactive
Error setting PasswordEntry's value. No such entry.

• I then try another syntax to create a file with the password in plaintext in it:

# engine-config -s PasswordEntry --admin-pass-file=/tmp/mypass
Error setting PasswordEntry's value. No such entry.
