Fabric Setup for Azure AD LDAPS

This authentication setup must be done from the Management Center using Azure AD (Active Directory), and via LDAP over SSL (LDAPS). Carry out the following:

Prerequisites

• A user must be set up so you can query the AD.

• From your IT or AD administrator, you must get the following parameters:

  • user & password
  • user group
  • admin_dn
  • users_base_dn
  • AD certificates in cer format and password as needed

  Below is an example of such parameters:

  • user: k2vfabric
  • user password: Q1w2e3r4t5
  • user group: K2vtdaadmin
  • admin_dn: CN=K2vtdaadmin,cn=users,DC=k2vfabric
  • users_base_dn: CN=Users,DC=k2vfabric,DC=local
  • AD (LDAPS mode): k2-fabric-ldap.k2vfabric.local
  • AD port: 636

Steps

The following steps must be carried out on all Fabric nodes by the root user:

• Update the /etc/hosts (if you cannot resolve the AD's DNS)

  echo "10.21.1.134 k2-fabric-ldap.k2vfabric.local" >> /etc/hosts

• Connect as fabric user

• Update the admin_privileges file on one fabric node only (the one that you will start with first).

  In this file we will insert the name of group that the user will use as fabric admin, and the AD to which the user belongs. In our example K2vtdaadmin

   cd $K2_HOME/
   echo "K2vtdaadmin" > $K2_HOME/config/admin_privileges

• Config Fabric's config.ini file as follows:

   cd $K2_HOME/
   sed -i "s@#SERVER_AUTHENTICATOR=.*@SERVER_AUTHENTICATOR=adldap@" $K2_HOME/config/config.ini
   sed -i "s@#url=.*@url=ldaps://k2-fabric-ldap.k2vfabric.local:636@" $K2_HOME/config/config.ini
   sed -i "s@#admin_dn=.*@admin_dn=CN=K2vtdaadmin,cn=users,DC=k2vfabric,DC=local@" $K2_HOME/config/config.ini
   sed -i "s@#admin_password=.*@admin_password=Q1w2e3r4t5@" $K2_HOME/config/config.ini
   sed -i "s@#users_base_dn=.*@users_base_dn=CN=Users,DC=k2vfabric,DC=local@" $K2_HOME/config/config.ini 

The following steps are unique to LDAPS (as opposed to LDAP):

• Import an LDAPS certificate to the java truststore
• If Fabric is not hardened run the following:

keytool -importcert -file root_cer.cer -keystore apps/java/jre/lib/security/cacerts -alias "ldap"

• You will be prompted for a password. Use changeit
• When you are prompted for a confirmation, input yes

See this example:

• If Fabric is hardened, run the following:

keytool -importcert -file root_cer.cer -keystore .cassandra_ssl/cassandra.truststore -alias "ldap"

• You will be prompted for a password. Use Q1w2e3r4t5
• When you are prompted for a confirmation, input yes
