After installing the Policy Server, to configure correctly the Policy Store, the Policy Server management console needs to be opened.
When defining the Policy Store IP, port and credentials to connect to it (1), and clicking on the "Apply" button, the smconsole freezes.
To modify the information to connect to the Policy Store, the Policy Server writes password information in the sm.registry.
This information is encrypted and to encrypt it, the smconsole needs entropy.
Create the symbolic link for the /dev/random to /dev/urandom to solve the issue (2). The smconsole will work as expected.
Commands to create the symbolic link:
# mv /dev/random /dev/random
# ln -s /dev/urandom /dev/random
