From Dekho 3.2 onwards each role created in Dekho has a new field: ROLETYPEID. This field was added to support the ability to change the name of the Dekho Administrative Role to comply with LDAP group naming policies if required.
Upon upgrade any custom roles added to Dekho will be given a default value of null. You are not required to update the ROLETYPEID for your custom roles at upgrade but esri Australia advises that you review your custom roles and apply an appropriate ROLETYPEID:
§ Default - 0
§ Administrative - 1
§ User - 2
