ldifwrite is intended for use only on OID "application data", not the schema or operational attributes and values (e.g., cn=catalogs, cn=changelog, etc.). Keep in mind that in order to use the command-line utility, you will need to know and use the ODS database username and password. The syntax for the ldifwrite command is:

ldifwrite -c <db_connect_string> -b <base DN> -f <filename>

Exporting Application Data and Values

You can type the following commands to export OID application data using ldapwrite:

# ldifwrite -c OIDDB_ALEX -b "o=airius.com" -f airius.ldif
This tool can only be executed if you know database user password for OiD
Enter OiD Password :: ods

Exporting Schema or Operational Attributes and Values

As previously mentioned, you cannot use ldifwrite to write out schema or operational data. In order to extract schema and operational data, you will need to use ldapsearch (described below). Trying to perform a search of this type, will result in the following error:

# ldifwrite -c OIDDB_ALEX -b "cn=subschemaSubentry" -f alex_oid_schema.ldif
This tool can only be executed if you know database user password for OiD
Enter OiD Password :: ods
Base DN cn=subschemasubentry not found.

The syntax for the ldifsearch command, while writing out to an LDIF file is:

ldapsearch -L -D "cn=orcladmin" -w "welcome" -h <host> -p <port> -b <base DN> -s <Search Scope (base | one | sub)> "<Search Filter>" > output_file.ldif

Exporting Application Data and Values

You can type the following commands to export OID application data using ldapsearch:

# ldapsearch -L -D "cn=orcladmin" -w "welcome" -h alex -p 389 -b "o=airius.com" -s sub "objectclass=*" > airius.ldif

Exporting Schema or Operational Attributes and Values

As previously mentioned, you cannot use ldifwrite to write out schema or operational data. You can only use to perform this type of operation. To export the schema or operational attributes and values, you need to use ldapsearch with the -L option as follows:

# ldapsearch -L -D "cn=orcladmin" -w "welcome" -h alex -p 389 -b "cn=subschemaSubentry" -s base "objectclass=*" > alex_oid_schema.ldif
