NAME

ldif - LDAP Data Interchange Format
 

DESCRIPTION

This manual page provides a basic description of LDIF. A formal specification of LDIF is published in RFC 2849.  

ENTRY RECORDS

LDIF entry records are used to represent directory entries. The basic form of an entry record is:

        dn: <distinguished name>
        <attrdesc>: <attrvalue>
        <attrdesc>: <attrvalue>
        <attrdesc>:: <base64-encoded-value>
        <attrdesc>:< <URL>
        ...

The value may be specified as UTF-8 text or as base64 encoded data, or a URI may be provided to the location of the attribute value.

A line may be continued by starting the next line with a single space or tab, e.g.,

        dn: cn=Barbara J Jensen,dc=exam
         ple,dc=com

Lines beginning with a sharp sign ('#') are ignored.

Multiple attribute values are specified on separate lines, e.g.,

        cn: Barbara J Jensen
        cn: Babs Jensen

If an value contains a non-printing character, or begins with a space or a colon ':', the <attrtype> is followed by a double colon and the value is encoded in base 64 notation. e.g., the value " begins with a space" would be encoded like this:

        cn:: IGJlZ2lucyB3aXRoIGEgc3BhY2U=

If the attribute value is located in a file, the <attrtype> is followed by a ':<' and a file: URI. e.g., the value contained in the file /tmp/value would be listed like this:

        cn:< file:///tmp/value

Multiple entries within the same LDIF file are separated by blank lines.  

ENTRY RECORD EXAMPLE

        dn: cn=Barbara J Jensen,dc=example,dc=com
        cn: Barbara J Jensen
        cn: Babs Jensen
        objectclass: person
        description:< file:///tmp/babs
        sn: Jensen

        dn: cn=Bjorn J Jensen,dc=example,dc=com
        cn: Bjorn J Jensen
        cn: Bjorn Jensen
        objectclass: person
        sn: Jensen

        dn: cn=Jennifer J Jensen,dc=example,dc=com
        cn: Jennifer J Jensen
        cn: Jennifer Jensen
        objectclass: person
        sn: Jensen
        jpegPhoto:: /9j/4AAQSkZJRgABAAAAAQABAAD/2wBDABALD
         A4MChAODQ4SERATGCgaGBYWGDEjJR0oOjM9PDkzODdASFxOQ
         ERXRTc4UG1RV19iZ2hnPk1xeXBkeFxlZ2P/2wBDARESEhgVG
        ...

Note that the description in Barbara Jensen's entry is read from file:///tmp/babs and the jpegPhoto in Jennifer Jensen's entry is encoded using base 64.  

CHANGE RECORDS

        dn: <distinguishedname>

        changetype: <[modify|add|delete|modrdn]>

Finally, the change information itself is given, the format of which depends on what kind of change was specified above. For a changetype of modify, the format is one or more of the following:

        add: <attributetype>
        <attrdesc>: <value1>
        <attrdesc>: <value2>
        ...
        -

Or, for a replace modification:

        replace: <attributetype>
        <attrdesc>: <value1>
        <attrdesc>: <value2>
        ...
        -

If no attributetype lines are given to replace, the entire attribute is to be deleted (if present).

Or, for a delete modification:

        delete: <attributetype>
        <attrdesc>: <value1>
        <attrdesc>: <value2>
        ...
        -

If no attributetype lines are given to delete, the entire attribute is to be deleted.

For a changetype of add, the format is:

        <attrdesc1>: <value1>
        <attrdesc1>: <value2>
        ...
        <attrdescN>: <value1>
        <attrdescN>: <value2>

For a changetype of modrdn or moddn, the format is:

        newrdn: <newrdn>
        deleteoldrdn: 0 | 1
        newsuperior: <DN>

where a value of 1 for deleteoldrdn means to delete the values forming the old rdn from the entry, and a value of 0 means to leave the values as non-distinguished attributes in the entry. The newsuperior line is optional and, if present, specifies the new superior to move the entry to.

For a changetype of delete, no additional information is needed in the record.

Note that attribute values may be presented using base64 or in files as described for entry records. Lines in change records may be continued in the manner described for entry records as well.  

CHANGE RECORD EXAMPLE

        dn: cn=Babs Jensen,dc=example,dc=com
        changetype: add
        objectclass: person
        objectclass: extensibleObject
        cn: babs
        cn: babs jensen
        sn: jensen

        dn: cn=Babs Jensen,dc=example,dc=com
        changetype: modify
        add: givenName
        givenName: Barbara
        givenName: babs
        -
        replace: description
        description: the fabulous babs
        -
        delete: sn
        sn: jensen
        -

        dn: cn=Babs Jensen,dc=example,dc=com
        changetype: modrdn
        newrdn: cn=Barbara J Jensen
        deleteoldrdn: 0
        newsuperior: ou=People,dc=example,dc=com

        dn: cn=Barbara J Jensen,ou=People,dc=example,dc=com
        changetype: delete
