Make sure you have working SSO install before applying these configurations
Enable SSL for LDAP
This example is done with self-signed certificate. It is always better to use publicly trusted certificate here.
Become root:
sudo su -Stop any IDS applications that is running in all instances:
systemctl stop wildfly.service
systemctl stop ubilogin-server.service
systemctl stop ubilogin-directory.serviceCreate new self-signed certificate chain:
# Create a temporary directory for certificate creation (name does not matter)
mkdir ~/ssl_cert
cd ~/ssl_cert
# Create certificate authority
openssl req -x509 \
-sha512 \
-days 3650 \
-nodes \
-newkey rsa:4096 \
-subj "/CN=localhost/C=FI/L=Espoo" \
-keyout cakey.pem -out cacert.pem
# Create server private key
openssl genrsa -out serverkey.pem 4096
# Generate certificate signging request
cat << EOF > servercsr.cnf

# View generated cert
openssl x509 -noout -in servercert.pem -textCheck that you do not have the certificate imported to cacerts:
Import the newly generated certificate to SSO Tomcat:
Check cacerts after import:
Result after the import:
Change ownership for generated files:
Change unix.config so that it will use ldaps:// instead of ldap:// as a connection:
Result should be something like this:
Once done, run SSO setup.sh again:
Once done, edit slapd.conf before updating LDAP configuration:
If any errors occurs, one can always run setup.sh again to reverse below changes to original defaults.
Reconfigure LDAP:
Update SSO configurations:
Restart services:
