Issue/Introduction

Problem:

Why do I have suddenly have a problem to login with the AdminUI on Linux OS, even after a re-registration?

Environment:

All CA Single Sign-On AdminUI versions

Cause:

You get problem to login because the OS entropy is too low.

Resolution:

You have to configure the OS to give more entropy.

As pre-requisite, the system should have enough entropy when running on Linux.
You need to check the symbolic link (/dev/random -> /dev/urandom) and create it if does not exists:

#ls -l /dev/random
crw-rw-rw- 1 root root 1, 8 Mar 14 10:47 /dev/random

-> show that symbolic link does not exists

 # ls -l /dev/random
lrwxrwxrwx 1 root root 12 Mar 17 14:35 /dev/random -> /dev/urandom

-> show that symbolic link exists

To create it:

1. you need to remove the the /dev/random file before.
mv /dev/random /dev/random.org

2. create the symbolic link
ln -s /dev/urandom /dev/random

Then restart the AdminUI and you should be able to login.

Additional Information:

The symbolic link may disappear on startup.
