Editing Guidelines

  • Edit this property on Teradata clients.
  • If Teradata Database runs on Linux, you must set MutualAuthentication to yes for KRB5 or SPNEGO.
  • If you want user logons through Unity to behave the same as user logons direct to the database, then the property setting for KRB5 and LDAP should be the same on Unity and on all connected database systems.
  • If you edit the preset value of this property on a mechanism that does not currently support it, TDGSS ignores the edit.
  • Do not modify the TDNEGO setting for this property.
