Multitenancy in WebLogic 12c Part -1: Security Realm for Partition Domain

In the new ear of  Multi-tenancy environment with WebLogic the application server software it self changed a lot internally to support the Partition based domains which supporting existing features as well. When we create a new SecurityRealm for a Partition, we need to create the following MBeans :

Let me begin with sample Training project where it runs with Online and Corporate training partitions. Here in this post we can configure security realm for each partition.
  • Authenticator
  • Role
  • Identity Asserter
  • Role Mapper
  • Authorizer
  • Adjucator
  • Auditor
  • Credential Mapper
  • Certificate Path Provider
  • Password Validator
WebLogic Multi-tenancy - SecurityRealm configuration


Lets make re-usable module so that everyone can use the function as it is. The changes could be in the main module only. Further simplification you could also move the values into a separate properties file.


def create_securityRealm4partition(realmName):
 
 security = cmo.getSecurityConfiguration()
 print 'realm name is ' + realmName
 realm = security.createRealm(realmName)
 
 # ATN
 atnp = realm.createAuthenticationProvider('ATNPartition','weblogic.security.providers.authentication.DefaultAuthenticator')
 atna = realm.createAuthenticationProvider('ATNAdmin','weblogic.security.providers.authentication.DefaultAuthenticator')
 
 # IA
 ia = realm.createAuthenticationProvider('IA','weblogic.security.providers.authentication.DefaultIdentityAsserter')
 ia.setActiveTypes(['AuthenticatedUser'])
 
 # ATZ/Role
 realm.createRoleMapper('Role','weblogic.security.providers.xacml.authorization.XACMLRoleMapper')
 realm.createAuthorizer('ATZ','weblogic.security.providers.xacml.authorization.XACMLAuthorizer')
 
 # Adjudicator
 realm.createAdjudicator('ADJ','weblogic.security.providers.authorization.DefaultAdjudicator')
 
 # Auditor
 realm.createAuditor('AUD','weblogic.security.providers.audit.DefaultAuditor')

 # Credential Mapper
 realm.createCredentialMapper('CM','weblogic.security.providers.credentials.DefaultCredentialMapper')
 
 # Cert Path
 realm.setCertPathBuilder(realm.createCertPathProvider('CP','weblogic.security.providers.pk.WebLogicCertPathProvider'))
 
 # Password Validator
 pv = realm.createPasswordValidator('PV', 'com.bea.security.providers.authentication.passwordvalidator.SystemPasswordValidator')
 pv.setMinPasswordLength(8)
 pv.setMinNumericOrSpecialCharacters(1)

def main():
 connect("weblogic","welcome1","t3://192.168.33.100:6100")
 edit()
 startEdit()

 create_securityRealm4partition('Online_Realm')
 create_securityRealm4partition('Corporate_Realm')

 save()
 activate()
 disconnect()
main()



 wlst createSecurityRealm.py


SecurityRealm using WLST
Configure Security realm for partitions using WLST Script createSecurityRealm.py 

On the other hand you can see the WebLogic Admin console output as well:
