• Registering NSX Manager to vCenter Server fails
• Configuring the SSO Lookup Service fails
• You may see errors similar to:
  • nested exception is java.net.UnknownHostException: vc.local( vc.corp.local )
  • NSX Management Service operation failed.( Initialization of Admin Registration Service Provider failed. Root Cause: Error occurred while registration of lookup service, com.vmware.vim.sso.admin.exception.InternalError: General failure.
  • com.vmware.vshield.vsm.security.service.impl.SamlTokenSSOAuthenticator : SSO is not configured or initialized properly so cannot authenticate user.

This issue occurs due to one of these reasons:

• Connectivity issues between the NSX Manager to vCenter Server.
• DNS is not configured properly on NSX Manager or vCenter Server.
• Firewall may be blocking this connection.
• Time is not synchronized between NSX Manager and vCenter Server.
• If you use Single Sign-On (SSO) and you do not have administrative rights.

• Connectivity issue
  
  Verify the connectivity from the NSX Manager to the vCenter Server.
  
  Ping from NSX Manager to the vCenter Server with the IP address and FQDN to check for routing, or static, or default route in NSX Manager, using this command:
  
  nsxmgr-l-01a# show ip route
  
  Where, Codes:
  K – kernel route,
  C – connected,
  S – static
  > – selected route,
  * – FIB route
  
  S>* 0.0.0.0/0 [1/0] via 192.168.110.2, mgmt
  
  C>* 192.168.110.0/24 is directly connected, mgmt
   

• DNS Issue
  
  Verify if DNS is getting resolved from NSX Manager to vCenter Server.
  
  Ping from NSX Manager to vCenter Server with FQDN using this command:

  nsxmgr-l-01a# ping vc-l-01a.corp.local
  
  You see similar output:
  
  PING vc-l-01a.corp.local (192.168.110.22): 56 data bytes
  
  64 bytes from 192.168.110.22: icmp_seq=0 ttl=64 time=0.576 ms
  
  If this does not work, navigate to Manage > Network > DNS Servers in NSX Manager and configure DNS.
  
  
  
   

• Firewall Issue
  
  If you have firewall between NSX Manager and vCenter Server, verify it allows SSL on TCP/443. Also, allow ping to check connectivity.
  
  Ports required for NSX Communication
  
  These ports must be open on NSX Manager:
   

  Port	Required for
  443/TCP	Downloading the OVA file on the ESXI host for deployment Using REST APIs Using the NSX Manager user interface
  80/TCP	Initiating connection to the vSphere SDK Messaging between NSX Manager and NSX host modules
  1234/TCP	Communication between NSX Controller and NSX Manager
  5671	Rabbit MQ (messaging bus technology)
  22/TCP	Console access (SSH) to CLI. Note: By default, this port is closed.

  
  
   

• NTP issue
  
  Verify that time is synchronized between vCenter Server and NSX Manager.

  

  To determine the time on the NSX Manager, run this command from the CLI:

  nsxmgr-l-01a# show clock
  
  You see similar output:
  
  Tue Nov 18 06:51:34 UTC 2014
  
  To determine the time on the vCenter Server, run this command on the CLI:

   

  vc-l-01a:~ # date
   

  You see similar output:
  
  Tue Nov 18 06:51:31 UTC 2014
  
  Note: After configuration of Time settings, restart the appliance.
   

• User permission issue
  
  To register to vCenter Server or SSO Lookup Service, you must have administrative rights.

  Try to work with default account:
  
  administrator user: [email protected]

• Reconnect SSO by entering the credentials.
