Can I add pwdMaxlength attribute to OpenLDAP password policy (ppolicy)?

Issue

• Can I set Maximum Length for password in (ppolicy) password policy configured in OpenLDAP?
• I have modified the ppolicy.schema schema and included pwdMaxlength attribute to configure Maximum Length for password but it is not working as expected. i.e:

* Copied below lines in /etc/openldap/schema/ppolicy.schema

1-   5.2.7. pwdMaxLength


   When quality checking is enabled, this attribute holds the maximum number of characters that may be used in a password.  If this attribute is not present, no maximum password length will be enforced.  If the server is unable to check the length (due to a hashed password or otherwise), the server will, depending on the  value of the pwdCheckQuality attribute, either accept the password without checking it ('0' or '1') or refuse it ('2').

         ( 1.3.6.1.4.1.42.2.27.8.1.31
         NAME 'pwdMaxLength'
         EQUALITY integerMatch
         SYNTAX 1.3.6.1.4.1.1466.115.121.1.27
         SINGLE-VALUE )

2] Then add pwdMaxLength after pwdMinLength

5.1. The pwdPolicy Object Class


   This object class contains the attributes defining a password policy
   in effect for a set of users.  Section 10 describes the
   administration of this object, and the relationship between it and
   particular objects.

         ( 1.3.6.1.4.1.42.2.27.8.2.1

         AUXILIARY
         MUST ( pwdAttribute )
         MAY ( pwdMinAge $ pwdMaxAge $ pwdInHistory $ pwdCheckQuality $
         pwdMinLength $ pwdMaxLength $ pwdExpireWarning $
