From the man pages ldapadd is just a hardlink to ldapmodify, but I tried and got the same error ldapadd -Y EXTERNAL -H ldapi:/// -v -f ldapMdynalist.ldif ldap_initialize( ldapi:///??base ) SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 add olcModuleLoad:     {0}/usr/lib64/openldap/memberof.la
The above is invalid. I strongly advise you to read the documentation.Also, you should not be touching or creating any files inside the cn=config database.
