-n Show what would be done, but don't actually perform the search. Useful for debugging in
conjunction with -v.
|
-c Continuous operation mode. Errors are reported, but ldapsearch will continue with searches. The
default is to exit after reporting an error. Only useful in conjunction with -f.
|
-u Include the User Friendly Name form of the Distinguished Name (DN) in the output.
|
-v Run in verbose mode, with many diagnostics written to standard output.
|
-t[t] A single -t writes retrieved non-printable values to a set of temporary files. This is useful for
dealing with values containing non-character data such as jpegPhoto or audio. A second -t writes
all retrieved values to files.
|
-T path
Write temporary files to directory specified by path (default: /var/tmp/)
|
-F prefix
URL prefix for temporary files. Default is file://path where path is /var/tmp/ or specified with
-T.
|
-A Retrieve attributes only (no values). This is useful when you just want to see if an attribute is
present in an entry and are not interested in the specific values.
|
-L Search results are display in LDAP Data Interchange Format detailed in ldif(5). A single -L
restricts the output to LDIFv1.
A second -L disables comments. A third -L disables printing of the LDIF version. The default is
to use an extended version of LDIF.
|
-M[M] Enable manage DSA IT control. -MM makes control critical.
|
-S attribute
Sort the entries returned based on attribute. The default is not to sort entries returned. If
attribute is a zero-length string (""), the entries are sorted by the components of their
Distinguished Name. See ldap_sort(3) for more details. Note that ldapsearch normally prints out
entries as it receives them. The use of the -S option defeats this behavior, causing all entries
to be retrieved, then sorted, then printed.
|
-d debuglevel
Set the LDAP debugging level to debuglevel. ldapsearch must be compiled with LDAP_DEBUG defined
for this option to have any effect.
|
-f file
Read a series of lines from file, performing one LDAP search for each line. In this case, the
filter given on the command line is treated as a pattern where the first and only occurrence of %s
is replaced with a line from file. Any other occurrence of the the % character in the pattern
will be regarded as an error. Where it is desired that the search filter include a % character,
the character should be encoded as \25 (see RFC 4515). If file is a single - character, then the
lines are read from standard input. ldapsearch will exit when the first non-successful search
result is returned, unless -c is used.
|
-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 authentication.
|
-H ldapuri
Specify URI(s) referring to the ldap server(s); a list of URI, separated by whitespace or commas
is expected; only the protocol/host/port fields are allowed. As an exception, if no host/port is
specified, but a DN is, the DN is used to look up the corresponding host(s) using the DNS SRV
records, according to RFC 2782. The DN must be a non-empty sequence of AVAs whose attribute type
is "dc" (domain component), and must be escaped according to RFC 2396.
|
-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.
|
-b searchbase
Use searchbase as the starting point for the search instead of the default.
|
-s {base|one|sub|children}
Specify the scope of the search to be one of base, one, sub, or children to specify a base object,
one-level, subtree, or children search. The default is sub. Note: children scope requires LDAPv3
subordinate feature extension.
|
-a {never|always|search|find}
Specify how aliases dereferencing is done. Should be one of never, always, search, or find to
specify that aliases are never dereferenced, always dereferenced, dereferenced when searching, or
dereferenced only when locating the base object for the search. The default is to never
dereference aliases.
|
-P {2|3}
Specify the LDAP protocol version to use.
|
-e [!]ext[=extparam]
|
-E [!]ext[=extparam]
Specify general extensions with -e and search extensions with -E. ´!´ indicates criticality.
General extensions:
[!]assert=<filter> (an RFC 4515 Filter)
[!]authzid=<authzid> ("dn:<dn>" or "u:<user>")
[!]manageDSAit
[!]noop
ppolicy
[!]postread[=<attrs>] (a comma-separated attribute list)
[!]preread[=<attrs>] (a comma-separated attribute list)
abandon, cancel (SIGINT sends abandon/cancel; not really controls)
Search extensions:
[!]domainScope (domain scope)
[!]mv=<filter> (matched values filter)
[!]pr=<size>[/prompt|noprompt] (paged results/prompt)
[!]sss=[-]<attr[:OID]>[/[-]<attr[:OID]>...] (server side sorting)
[!]subentries[=true|false] (subentries)
[!]sync=ro[/<cookie>] (LDAP Sync refreshOnly)
rp[/<cookie>][/<slimit>] (LDAP Sync refreshAndPersist)
[!]vlv=<before>/<after>(/<offset>/<count>|:<value>) (virtual list view)
|
-l timelimit
wait at most timelimit seconds for a search to complete. A timelimit of 0 (zero) or none means no
limit. A timelimit of max means the maximum integer allowable by the protocol. A server may
impose a maximal timelimit which only the root user may override.
|
-z sizelimit
retrieve at most sizelimit entries for a search. A sizelimit of 0 (zero) or none means no limit.
A sizelimit of max means the maximum integer allowable by the protocol. A server may impose a
maximal sizelimit which only the root user may override.
|
-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.
