LDAPMODIFY(1)

NAME
ldapmodify, ldapadd - ldap modify entry and ldap add entry tools

SYNOPSIS
ldapmodify [-a] [-b] [-c] [-r] [-n] [-v] [-k] [-d debuglevel] [-D binddn] [-w passwd] [-h ldaphost] [-p ldapport] [-f file]

ldapadd [-b] [-c] [-r] [-n] [-v] [-k] [-K] [-d debuglevel] [-D binddn] [-w passwd] [-h ldaphost] [-p ldapport] [-f file]

DESCRIPTION
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.

-b  Assume that any values that start with a `/' are binary values and that the actual value is in a file whose path is specified in the place where values normally appear.

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

-r  Replace existing values by default.

-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.

-k  Use Kerberos authentication instead of simple authentication. It is assumed that you already have a valid ticket granting ticket. You must compile with KERBEROS defined for this option to have any effect.

-K  Same as -k, but only does step 1 of the kerberos bind. This is useful when connecting to a slapd and there is no x500dsa.hostname principal registered with your kerberos servers.

-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).

-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.

-D binddn
    Use binddn to bind to the X.500 directory. binddn should be a string-represented DN as defined in RFC 1779.

-w passwd
    Use passwd as the password for simple authentication.

-h ldaphost
    Specify an alternate host on which the ldap server is running.

-p ldapport
    Specify an alternate TCP port where the ldap server is listening.

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 slapd.replog(5), with the exceptions noted below.

If the first line of a record consists of a decimal number (entry id), it is ignored.

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 ldapmodify) and "modify" otherwise.

If changetype is "modify" and no "add:", "replace:", or "delete:" lines appear, the default is "replace" if the -r flag is set and "add" otherwise.

Note that the above exceptions to the slapd.replog(5) format allow ldif(5) entries to be used as input to ldapmodify or ldapadd.

ALTERNATIVE INPUT FORMAT
An alternative input format is supported for compatibility with older versions of ldapmodify. This format consists of one or more entries separated by blank lines, where each entry looks like:

    Distinguished Name (DN)
    attr=value
    [attr=value ...]

where attr is the name of the attribute and value is the value.

By default, values are added. If the -r command line flag is given, the default is to replace existing values with the new one. Note that it is permissible for a given attribute to appear more than once (for example, to add more than one value for an attribute). Also note that you can use a trailing `\' to continue values across lines and preserve newlines in the value itself (this is useful for modifying QUIPU iattr attributes among others).

attr should be preceded by a - to remove a value. The `=' and value should be omitted to remove an entire attribute.

attr should be preceded by a + to add a value in the presence of the -r flag.

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

    dn: cn=Modify Me, o=University of Michigan, c=US
    changetype: modify
    replace: mail
    mail: modme@terminator.rs.itd.umich.edu
    -
    add: title
    title: Grand Poobah
    -
    add: jpegPhoto
    jpegPhoto: /tmp/modme.jpeg
    -
    delete: description
    -

the command:

    ldapmodify -b -r -f /tmp/entrymods

will replace the contents of the "Modify Me" entry's mail attribute with the value "modme@terminator.rs.itd.umich.edu", add a title of "Grand Poobah", and the contents of the file "/tmp/modme.jpeg" as a jpegPhoto, and completely remove the description attribute. The same modifications as above can be performed using the older ldapmodify inout format:

    cn=Modify Me, o=University of Michigan, c=US
    mail=modme@terminator.rs.itd.umich.edu
    +title=Grand Poobah
    +jpegPhoto=/tmp/modme.jpeg
    -description

and the command:

    ldapmodify -b -r -f /tmp/entrymods

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

    dn: cn=Barbara Jensen, o=University of Michigan, c=US
    objectClass: person
    cn: Barbara Jensen
    cn: Babs Jensen
    sn: Jensen
    title: the world's most famous mythical manager
    mail: bjensen@terminator.rs.itd.umich.edu
    uid: bjensen

the command:

    ldapadd -f /tmp/entrymods

will add a new entry for Babs Jensen, using the values from the file /tmp/newentry.

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

    dn: cn=Barbara Jensen, o=University of Michigan, c=US
    changetype: delete

the command:

    ldapmodify -f /tmp/entrymods

will remove Babs Jensen's entry.

DIAGNOSTICS
Exit status is 0 if no errors occur. Errors result in a non-zero exit status and a diagnostic message being written to standard error.

BUGS
There is no interactive mode, but there probably should be.
