Prerequisities

All the steps before this step in either Windows scalability and high availability setup - SSO or Linux scalability and high availability setup - SSO must have been done.



To configure SSO to use Redis backed session storage, you need to modify data in SSO configuration database (Ubilogin directory):

  • Create a new ubiloginService entry in cn=Services,ou=System with following attributes:
    • ubiloginClassname → com.ubisecure.ubilogin.session.manager.redis.SessionManagerFactoryRedis
    • ubiloginConfString → url <URL of the Redis service, in form redis://[address]:[port]>
      • Possible to set separate entries for each seed node in the cluster, as shown in the example below.
      • The seed nodes don't need to contain all the nodes in the cluster, as SSO will discover the other nodes during runtime through Redis protocol.
      • At least one of the seed nodes needs to be online during SSO startup. Otherwise SSO fails to boot.
    • ubiloginConfString → password <password for the Redis service>
  • Link the created ubiloginService to the cn=ServerSession,ou=System entry using ubiloginServiceDN attribute

For example:

dn: cn=SessionManagerFactoryRedis,cn=Services,ou=System,@suffix@
changetype:add
objectClass: ubiloginService
cn: SessionManagerFactoryRedis
ubiloginClassName: com.ubisecure.ubilogin.session.manager.redis.SessionManagerFactoryRedis
ubiloginConfString: url redis://redisnode1.example.com:7000
ubiloginConfString: url redis://redisnode1.example.com:7001
ubiloginConfString: url redis://redisnode2.example.com:7000
ubiloginConfString: url redis://redisnode2.example.com:7001
ubiloginConfString: url redis://redisnode3.example.com:7000
ubiloginConfString: url redis://redisnode3.example.com:7001
ubiloginConfString: password SecretPassword1

dn: cn=ServerSession,ou=System,@suffix@
changetype: modify
replace: ubiloginServiceDN
ubiloginServiceDN: cn=SessionManagerFactoryRedis,cn=Services,ou=System,@suffix@
-

Note that @suffix@ must be expanded to the value of attribute suffix in win32.config.

The change can be done using for example Apache DirectoryStudio, or you can create an ldif file to change the file, and load the data using import script:

./ldap/openldap/import.sh ldap/[name of file containing the changes].ldif
