Although not recommended, you can use the dsconfig tool to disable the schema checking. This feature only applies to public backends. Schema checking is enforced on private backends, such as changes to the Configuration, Schema, Task, and others. An admin action alert will be generated when attempting to disable schema checking using dsconfig interactive or non-interactive mode. The alert provides alternatives to disabling schema checking.
  1. Run the dsconfig command and specify the set-global-configuration-prop subcommand to disable the check-schema property.
    $ bin/dsconfig --no-prompt set-global-configuration-prop \ 
      --set check-schema:false

    The system generates an admin action alert providing alternate options to disabling schema checking. Press Enter to continue the process or following one of the suggested tasks:

    One or more configuration property changes require administrative action or 
    Those properties include:
      *   check-schema: Schema checking should only be disabled as a last resort 
          since disabling schema checking harms performance and can lead to 
          unexpected behavior in the server as well as the applications that 
          access it. There are less severe options for addressing schema issues:                         
      1.  Update the data to conform to the server schema.
      2.  Modify the server schema to conform to the data. Contact support before 
          modifying the server's default schema.
      3.  Change the single-structural-objectclass-behavior property to allow 
          entries to have no structural object class or multiple structural object 
      4.  Change the invalid-attribute-syntax-behavior property to allow attribute 
          values to violate their attribute syntax.    
      5.  Change the allow-zero-length-values property of the Directory String 
          Attribute Syntax configuration to allow attributes with this syntax to 
          have a zero length value.
