DESCRIPTION         top

       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

       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         top

       -V[V]  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.

       -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

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

       -c     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.

       -M[M]  Enable manage DSA IT control.  -MM makes control critical.

       -x     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.

       -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

       -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.

       -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 general options.

              General options:
                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.

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

       -Q     Enable SASL Quiet mode.  Never prompt.

       -N     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.

       -Z[Z]  Issue StartTLS (Transport Layer Security) extended operation.
              If you use -ZZ, the command will require the operation to be

INPUT FORMAT         top

       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).

EXAMPLES         top

       Assuming that the file /tmp/entrymods exists and has the contents:

           dn: cn=Modify Me,dc=example,dc=com
           changetype: modify
           replace: mail
           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 "", 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
           uid: bjensen

       the command:

           ldapadd -f /tmp/newentry

       will add a new entry for Babs Jensen, using the values from the file

       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         top

       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.
