DXsearch Tool—Search a Directory

Use the DXsearch tool to search within a specified directory using defined filters. The utility lets you specify search output as LDIF or text, or can write each returned attribute to a file.

This command has the following format:

dxsearch [options] filter [attributelist]

options

Denotes one or more of the following options:

-a { never | always | search | find }

Sets alias dereferencing.

-A

Retrieves attribute names only (no values).

-b basedn

Specifies the base DN for the search.

-B

Does not suppress printing of non-ASCII values.

-c

Runs in continuous mode. Errors are reported, but the process is not stopped.

-d level [-d level...]

Sets the LDAP debug levels.

level

Defines the level of debugging as follows:

-1 Enable all debugging

0 No debugging

1 Trace function

2 Debug packet handling

4 Heavy trace debugging

8 Connection management

16 Print out packages sent and received

32 Search filter processing

64 Configuration file processing

128 Access control list processing

256 Stats log connections/operations/results

512 Stats log entries sent

1024 Print communication with shell backends

2048 Print entry parsing debugging

You can add numbers together to specify multiple debug levels at the same time. For example, a debug level of 6 specifies the debugging levels of both 2 and 4.

-D bindDN

Specifies the distinguished name of the user performing the bind.

-f filename

Specifies a file to read from, rather than standard input.

-h host

Specifies the directory host. If you do not specify this, the tool uses localhost instead.

-H LDAP_URI

Specifies the LDAP URI of the directory host. If you do not specify this, the tool uses localhost instead.

You can use an IPv6 address, as in the following example:

-H ldap://[2001:db8:0:1:99a4:6159:198f:b309]

-l timelimit

Specifies the time limit in seconds for each DAP operation.

-L

Prints entries in LDIF format (-B is implied).

-M

Does not multicast; limits search to a single directory.

-n

Shows what would be done, but does not actually do it. Use with the -v option for debugging.

-p dap-port

Specifies the port on directory host computer. If you do not specifiy this, the default of 102, the OSI port, is used.

You can combine the -H and -p arguments into a single argument. For example, you can replace the options on the first line with those on the second:

-H [2001:db8:0:1:99a4:6159:198f:b309] -p 19389
-H [2001:db8:0:1:99a4:6159:198f:b309]:19389

-s { base | one | sub}

Specifies search scope.

-t dir

Writes values to files in the specified directory.

-T

Times the search (no search results printed).

-v

Runs in verbose mode.

-w password

Specifies the bind password, which is used for simple authentication.

-z number-entries

Specifies the size limit (in entries) for search.

-Z [ssld_config_filename]

Specifies that the tool should start a TLS request.

Use -ZZ to require a successful response from the DSA.

ssld_config_filename

Specifies the name of the configuration file used by the -Z option. The default file is:

DXHOME/config/ssld/dxldap.conf

This configuration file is a text file. It must contain a line starting TLS_CACERT, and can optionally contain a second line starting TLS_REQCERT. Its format is as follows:

TLS_CACERT trusted_pem_file
[TLS_REQCERT {allow|demand|hard|never|try}]

In the configuration file, the lines have the following meaning:

TLS_CACERT trusted_pem_file

Specifies the file that contains certificates for all of the Certificate Authorities the client will recognize.

trusted_pem_file

Species the trusted pem file.

This must be an absolute reference to a full path, without environment variables.

Do not enclose trusted_pem_file in quotes.

[TLS_REQCERT {allow|demand|hard|never|try} ]

Specifies what checks to perform on server certificates in a TLS session, if any.

If this line is missing, the system uses TLS_REQCERT demand

The keywords have the following meaning:

• allow - The client will request a server certificate and if no certificate is provided, the session proceeds normally. If a bad certificate is provided, it will be ignored and the session proceeds normally.
• demand - The client will request a server certificate and if no certificate is provided, or a bad certificate is provided, the session is immediately terminated. This is the default setting.
• hard - This is a synonym for demand.
• never - The client will not request or check any server certificate.
• try - The client will request a server certificate and if no certificate is provided, the session proceeds normally. However, if a bad certificate is provided, the session immediately terminates.

Example: dxldap.conf file on a Windows System, Specifying the TLS_REQCERT Setting

TLS_CACERT  c:\program files\CA\Directory\dxserver\config\ssld\trusted.pem
TLS_REQCERT allow

Example: dxldap.conf file on a UNIX System, Using the Default TLS_REQECRT Setting

TLS_CACERT  /opt/CA/Directory/dxserver/config/ssld/trusted.pem

filter

An RFC2254-compliant LDAP search filter.

attributelist

Specifies a space-separated list of attributes to retrieve. If no attribute list is given, all attributes are retrieved.

Example: Search and Results

This example uses the Democorp sample directory supplied with CA Directory. You can repeat this example as a training exercise.

Use the following command to search:

%dxsearch -L -h 192.168.19.202:19389 "(sn=horsfall)"

The results appear like this:

dn: cn=Murray HORSFALL,ou=Repair,ou=Operations,o=Democorp,c=AU
oc: organizationalPerson
oc: newPilotPerson
oc: quipuObject
cn: Murray HORSFALL
sn: HORSFALL
title: Information Technology Manager
telephone: 797 8877
description: Replacements
mail: Murray.HORSFALL@Democorp.com
postalAddress: 173 Toorak Pde $ Berkeley NSW
postalCode: 2506

If you send the output to an LDIF file, you can edit the file contents and use the DXmodify tool to implement the changes.

dxsearch -L -h yourhost:19389 "(sn=horsfall)" > h-modify.ldi
