ldapmodify
is a shell-accessible interface to the
ldap_modify(3)
and
ldap_add(3)
library calls.
ldapadd
is implemented as a hard link to the ldapmodify tool. When invoked as
ldapadd
the -a (add new entry) flag is turned on automatically.
ldapmodify
opens a connection to an LDAP server, binds, and modifies or adds entries.
The entry information is read from standard input or from file through
the use of the -f option.
OPTIONS
-a
Add new entries. The default for
ldapmodify
is to modify existing entries. If invoked as
ldapadd,
this flag is always set.
-c
Continuous operation mode. Errors are reported, but
ldapmodify
will continue with modifications. The default is to exit after
reporting an error.
-S file
Add or change records which where skipped due to an error are written to file
and the error message returned by the server is added as a comment. Most useful in
conjunction with -c.
-n
Show what would be done, but don't actually modify entries. Useful for
debugging in conjunction with -v.
-v
Use verbose mode, with many diagnostics written to standard output.
-F
Force application of all changes regardless of the contents of input
lines that begin with
replica:
(by default, replica: lines are compared against the LDAP server host
and port in use to decide if a replog record should actually be applied).
-M[M]
Enable manage DSA IT control.
-MM
makes control critical.
-d debuglevel
Set the LDAP debugging level to debuglevel.
ldapmodify
must be compiled with LDAP_DEBUG defined for this option to have any effect.
-f file
Read the entry modification information from file instead of from
standard input.
-x
Use simple authentication instead of SASL.
-D binddn
Use the Distinguished Name binddn to bind to the LDAP directory.
-W
Prompt for simple authentication.
This is used instead of specifying the password on the command line.
-w passwd
Use passwd as the password for simple authentication.
-y passwdfile
Use complete contents of passwdfile as the password for
simple authentication.
-H ldapuri
Specify URI(s) referring to the ldap server(s); only the protocol/host/port
fields are allowed; a list of URI, separated by whitespace or commas
is expected.
-h ldaphost
Specify an alternate host on which the ldap server is running.
Deprecated in favor of -H.
-p ldapport
Specify an alternate TCP port where the ldap server is listening.
Deprecated in favor of -H.
-P 2|3
Specify the LDAP protocol version to use.
-O security-properties
Specify SASL security properties.
-I
Enable SASL Interactive mode. Always prompt. Default is to prompt
only as needed.
-Q
Enable SASL Quiet mode. Never prompt.
-U authcid
Specify the authentication ID for SASL bind. The form of the ID
depends on the actual SASL mechanism used.
-R realm
Specify the realm of authentication ID for SASL bind. The form of the realm
depends on the actual SASL mechanism used.
-X authzid
Specify the requested authorization ID for SASL bind.
authzid
must be one of the following formats:
dn:<distinguished name>
or
u:<username>
-Y mech
Specify the SASL mechanism to be used for authentication. If it's not
specified, the program will choose the best mechanism the server knows.
-Z[Z]
Issue StartTLS (Transport Layer Security) extended operation. If you use
-ZZ, the command will require the operation to be successful.
INPUT FORMAT
The contents of file (or standard input if no -f flag is given on
the command line) should conform to the format defined in
ldif(1)
(LDIF as defined RFC 2849), or
slapd.replog(5)
(an extended form of LDIF)
with the exceptions noted below.
Lines that begin with "replica:" are matched against the LDAP server host
and port in use to decide if a particular replog record should be applied.
Any other lines that precede the "dn:" line are ignored.
The -F flag can be used to force
ldapmodify
to apply all of the replog changes, regardless of the presence or
absence of any "replica:" lines.
If no "changetype:" line is present, the default is "add" if the -a
flag is set (or if the program was invoked as
ldapadd)
and "modify" otherwise.
If changetype is "modify" and no "add:", "replace:", or "delete:" lines
appear, the default is "replace" for
ldapmodify(1)
and "add" for
ldapadd(1).
Note that the above exceptions to the
slapd.replog(5)
format allow
ldif(5)
entries to be used as input to
ldapmodify
or
ldapadd.
EXAMPLES
Assuming that the file
/tmp/entrymods
exists and has the contents:
dn: cn=Modify Me,dc=example,dc=com
changetype: modify
replace: mail
mail: modme@example.com
-
add: title
title: Grand Poobah
-
add: jpegPhoto
jpegPhoto:< file:///tmp/modme.jpeg
-
delete: description
-
the command:
ldapmodify -f /tmp/entrymods
will replace the contents of the "Modify Me" entry's
mail
attribute with the value "modme@example.com", add a
title
of "Grand Poobah", and the contents of the file "/tmp/modme.jpeg"
as a
jpegPhoto,
and completely remove the
description
attribute.
Assuming that the file
/tmp/newentry
exists and has the contents:
dn: cn=Barbara Jensen,dc=example,dc=com
objectClass: person
cn: Barbara Jensen
cn: Babs Jensen
sn: Jensen
title: the world's most famous mythical manager
mail: bjensen@example.com
uid: bjensen
the command:
ldapadd -f /tmp/newentry
will add a new entry for Babs Jensen, using the values from the
file
/tmp/newentry.
Assuming that the file
/tmp/entrymods
exists and has the contents:
dn: cn=Barbara Jensen,dc=example,dc=com
changetype: delete
the command:
ldapmodify -f /tmp/entrymods
will remove Babs Jensen's entry.
DIAGNOSTICS
Exit status is zero if no errors occur. Errors result in a non-zero
exit status and a diagnostic message being written to standard error.
