LDIF(5) File Formats Manual LDIF(5)
ldif - LDAP Data Interchange Format
The LDAP Data Interchange Format (LDIF) is used to represent LDAP
entries and change records in text form. LDAP tools, such as
ldapadd(1) and ldapsearch(1), read and write LDIF entry records.
ldapmodify(1) reads LDIF change records.
This manual page provides a basic description of LDIF. A formal
specification of LDIF is published in RFC 2849.
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
Other URI schemes (ftp,http) may be supported as well.
Multiple entries within the same LDIF file are separated by blank
lines.
Here is an example of an LDIF file containing three entries.
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

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.
LDIF change records are used to represent directory change
requests. Each change record starts with line indicating the
distinguished name of the entry being changed:
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.
The following sample LDIF file contains a change record of each
type of change.
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
The LDIF parser has been extended to support an include statement
for referencing other LDIF files. The include statement must be
separated from other records by a blank line. The referenced
file is specified using a file: URI and all of its contents are
incorporated as if they were part of the original LDIF file. As
above, other URI schemes may be supported. For example:
dn: dc=example,dc=com
objectclass: domain
dc: example
include: file:///tmp/example.com.ldif
dn: dc=example,dc=org
objectclass: domain
dc: example
This feature is not part of the LDIF specification in RFC 2849
but is expected to appear in a future revision of this spec. It
is supported by the ldapadd(1), ldapmodify(1), and slapadd(8)
commands.
ldap(3), ldapsearch(1), ldapadd(1), ldapmodify(1), slapadd(8),
slapcat(8), slapd-ldif(5).
