Hi,
Thanks for your suggestion.
was able to load backend modules after adding following lines to slapd.conf file
# Load dynamic backend modules:
modulepath /usr/lib/openldap
#moduleload back_mdb.la
#moduleload back_ldap.la
moduleload back_mdb
moduleload back_ldap
After making this change, my slaptest passed which was failing earlier.
/opt/hpe/nns/NVME-OF-Server/open-ldap/initial_config # slaptest -f
/etc/openldap/slapd.conf -F /etc/ldap/sns/slapd.d -d 256 -u
config file testing succeeded
/opt/hpe/nns/NVME-OF-Server/open-ldap/initial_config #
but the original issue still persists, as below:
/opt/hpe/nns/NVME-OF-Server/open-ldap/initial_config # ldapadd -x -D
'cn=config' -w secret -f create_sns_db.ldif
adding new entry "olcDatabase=mdb,cn=config"
ldap_add: Invalid syntax (21)
additional info: objectClass: value #0 invalid per syntax
/opt/hpe/nns/NVME-OF-Server/open-ldap/initial_config #
