entries don't get added according to the scehma file in LDAP browser

Hi, I have OpenLDAP version 2.4.11 configured in multimaster mode. Attached files is the schema file (core.schema) and configuration file for LDAP. I have modified core.schema file to make 'companyName' a mandatory parameter in objectClass 'organizationalUnit' When I add an entry using 'ldapadd' without providing parameter 'companyName', it is getting added in the LDAP which is not correct. It should give error of missing mandatory parameter. When this LDAP is working as single instance i.e. without multimaster mode, then while adding the same entry without parameter 'companyName', LDAP is showing error given below. ldap_add: Object class violation (65) additional info: object class 'organizationalUnit' requires attribute 'companyName' I don’t understand what is causing any difference. Please check and give any suggestion. Thanks, Gurjot Kaur "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed.
