KB-1767: How to adjoin when there are conflicting / duplicate SPNs in the forest

Auditing and Monitoring Service ,   Authentication Service ,   Mac & PC Management Service ,

adjoin fails with the following message:
  • One or more of the following SPNs already associated with other account in the forest


This can happen if there is an enterprise application, such as SAP, using the http SPN, which causes a conflict when adjoin is run.


Remove "http" from adclient.krb5.service.principals in /etc/centrifydc/centrifydc.conf.
The entry should now read:
  • adclient.krb5.service.principals:¬†ftp cifs nfs

Save the configuration and then run adjoin again.
