ldapmodify is a shell-accessible interface to the ldap_add_ext(3), ldap_modify_ext(3), ldap_delete_ext(3) and ldap_rename(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.



Print version info. If -VV is given, only the version information is printed.

-d debuglevel

Set the LDAP debugging level to debuglevel. ldapmodify must be compiled with LDAP_DEBUG defined for this option to have any effect.


Show what would be done, but don't actually modify entries.  Useful for debugging in conjunction with -v.


Use verbose mode, with many diagnostics written to standard output.


Add new entries.  The default for ldapmodify is to modify existing entries.  If invoked as ldapadd, this flag is always set.


Continuous operation mode.  Errors are reported, but ldapmodify will continue with modifications.  The default is to exit after reporting an error.

-f file

Read the entry modification information from file instead of from standard input.

-S file

Add or change records which were 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.


Enable manage DSA IT control. -MM makes control critical.


Use simple authentication instead of SASL.

-D binddn

Use the Distinguished Name binddn to bind to the LDAP directory. For SASL binds, the server is expected to ignore this value.


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.

-P {2|3}

Specify the LDAP protocol version to use.

-e [!]ext[=extparam]
-E [!]ext[=extparam]

Specify general extensions with -e and modify extensions with -E. ´!´ indicates criticality.

General extensions:

  [!]assert=<filter>    (an RFC 4515 Filter)
  !authzid=<authzid>    ("dn:<dn>" or "u:<user>")
  [!]bauthzid           (RFC 3829 authzid control)
  [!]postread[=<attrs>] (a comma-separated attribute list)
  [!]preread[=<attrs>]  (a comma-separated attribute list)
  abandon,cancel,ignore (SIGINT sends abandon/cancel,
  or ignores response; if critical, doesn't wait for SIGINT.
  not really controls)

Modify extensions:

-o opt[=optparam]]

Specify any ldap.conf(5) option or one of the following:

  nettimeout=<timeout>  (in seconds, or "none" or "max")
  ldif_wrap=<width>     (in columns, or "no" for no wrapping)
-O security-properties

Specify SASL security properties.


Enable SASL Interactive mode.  Always prompt.  Default is to prompt only as needed.


Enable SASL Quiet mode.  Never prompt.


Do not use reverse DNS to canonicalize SASL host name.

-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.


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) must conform to the format defined in ldif(5) (LDIF as defined in RFC 2849).


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.


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.
