default config file

Hello All, Noticing a difference in behavior of locating config file at the time of startup between 2.4.48 and 2.4.58. The 2.4.48 is a ubuntu supplied package while 2.4.58 is compiled with following options. ./configure --prefix=/opt/openldap \ --sysconfdir=/etc/ldap \ --localstatedir=/opt/openldap/var \ --libexecdir=/opt/openldap/lib \ --disable-static \ --enable-debug \ --with-tls=openssl \ --with-cyrus-sasl \ --enable-dynamic \ --enable-crypt \ --enable-spasswd \ --enable-slapd \ --enable-modules \ --enable-rlookups \ --enable-backends=mod \ --disable-ndb \ --disable-sql \ --disable-shell \ --disable-bdb \ --disable-hdb \ --enable-overlays=mod When started the slaps in debug mode, I see the following for 2.4.48 6077b590 backend_startup_one: starting "cn=config" 6077b590 ldif_read_file: read entry file: "/etc/ldap/slapd.d/cn=config.ldif” Essentially, looking for “cn=config”. However, after replacing the binaries with compiled version for 2.4.58, 6077b37d could not stat config file "/etc/ldap/slapd.d/slapd.conf": No such file or directory (2) I clearly notice that existing configuration file(s) are not considered with 2.4.58. Wondering what is the difference and how can I use the existing configuration files. Thanks
