Why do I have suddenly have a problem to login with the AdminUI on Linux OS, even after a re-registration?
All CA Single Sign-On AdminUI versions
You get problem to login because the OS entropy is too low.
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.
The symbolic link may disappear on startup.
