History
New in ColdFusion MX:
- This tag validates the query name in the
name
attribute.
- This tag does not support client-side sorting of query results. (It supports server-side sorting; use the
sort
and sortcontrol
attributes.)
- Server-side sorting results might be sorted slightly differently than in ColdFusion 5. If you attempt a sort against a server that does not support it, ColdFusion MX throws an error.
- The
filterconfig
and filterfile
attributes are deprecated. Do not use them in new applications. They might not work, and might cause an error, in later releases. If they are used, this tag throws an exception.
Attributes
Attribute |
Req/Opt |
Default |
Description |
server
|
Required
|
|
Host name or IP address of LDAP server.
|
port
|
Optional
|
389
|
Port
|
username
|
Required if secure = "CFSSL_BASIC"
|
(anonymous)
|
User ID
|
password
|
Required if secure = "CFSSL_BASIC"
|
|
Password that corresponds to user name. If secure = "CFSSL_BASIC" , V2 encrypts the password before transmission.
|
action
|
Optional
|
query
|
query : returns LDAP entry information only. Requires name , start , and attributes attributes.
add : adds LDAP entries to LDAP server. Requires attributes attribute.
modify : modifies LDAP entries, except distinguished name dn attribute, on LDAP server. Requires dn . See modifyType attribute.
modifyDN : modifies distinguished name attribute for LDAP entries on LDAP server. Requires dn .
delete : deletes LDAP entries on an LDAP server. Requires dn .
|
name
|
Required if action = "Query"
|
|
Name of LDAP query. The tag validates the value.
|
timeout
|
Optional
|
60
|
Maximum length of time, in seconds, to wait for LDAP processing.
|
maxRows
|
Optional
|
|
Maximum number of entries for LDAP queries.
|
start
|
Required if action = "Query"
|
|
Distinguished name of entry to be used to start a search.
|
scope
|
Optional
|
oneLevel
|
Scope of search, from entry specified in start attribute for action = "Query" .
- oneLevel: entries one level below entry.
- base: only the entry.
- subtree: entry and all levels below it.
|
attributes
|
Required if action = "Query", "Add", "ModifyDN" , or "Modify"
|
|
For queries: comma-delimited list of attributes to return. For queries, to get all attributes, specify "*" . If action = "add" or "modify" , you can specify a list of update columns. Separate attributes with a semicolon. If action = "ModifyDN" , ColdFusion passes attributes to the LDAP server without syntax checking.
|
filter
|
Optional
|
"objectclass = *"
|
Search criteria for action = "query" . List attributes in the form:
"(attribute operator value)" Example: "(sn = Smith)"
|
sort
|
Optional
|
|
Attribute(s) by which to sort query results. Use a comma delimiter.
|
sortControl
|
Optional
|
asc
|
- nocase: case-insensitive sort
- asc: ascending (a to z) case-sensitive sort
- desc: descending (z to a) case-sensitive sort
You can enter a combination of sort types; for example, sortControl = "nocase, asc" .
|
dn
|
Required if action = "Add", "Modify", "ModifyDN", or "delete"
|
|
Distinguished name, for update action. Example: "cn = Bob Jensen, o = Ace Industry, c = US"
|
startRow
|
Optional
|
1
|
Used with action = "query" . First row of LDAP query to insert into a ColdFusion query.
|
modifyType
|
Optional
|
replace
|
How to process an attribute in a multi-value list.
- add: appends it to any attributes
- delete: deletes it from the set of attributes
- replace: replaces it with specified attributes
You cannot add an attribute that is already present or that is empty.
|
rebind
|
Optional
|
No
|
- Yes: attempt to rebind referral callback and reissue query by referred address using original credentials.
- No: referred connections are anonymous
|
referral
|
Optional
|
|
Integer. Number of hops allowed in a referral. A value of 0 disables referred addresses for LDAP; no data is returned.
|
secure
|
Optional
|
|
Security to employ, and required information. One option:
- CFSSL_BASIC; certificate_db
- "CFSSL_BASIC" provides V2 SSL encryption and server authentication
- -certificate_db: certificate database file (Netscape cert7.db format). Absolute path or simple filename. See the Usage section.
|
separator
|
Optional
|
, [comma]
|
Delimiter to separate attribute values of multi-value attributes. Used by query , add , and modify actions, and by cfldap to output multi-value attributes. For example, if $ (dollar sign), the attributes attribute could be "objectclass = top$person" , where the first value of objectclass is "top ", and the second value is "person ". This avoids confusion if values include commas.
|
delimiter
|
Optional
|
|
Separator for attribute name-value pairs, if:
- the
attributes attribute specifies more than one item
- an attribute has the delimiter semicolon. For example:
mgrpmsgrejecttext;lang-en
Used by query , add , and modify actions, and by cfldap to output multi-value attributes. For example, if $ (dollar sign), you could specify this list of pairs with attributes:
"cn = Double Tree Inn$street = 1111 Elm;Suite 100
|
Usage
If you use the query
action, cfldap
creates a query object, allowing access to information in the query variables, as follows:
Variable name |
Description |
queryname.recordCount
|
Number of records returned by query
|
queryname.currentRow
|
Current row of query that cfoutput is processing
|
queryname.columnList
|
Column names in query
|
To use the security = "CFSSL_BASIC"
option, you must copy the cert7.db and/or key3.db key files to the default directory location of a user-installed LDAP directory; on Windows, the directory is C:\cfusion\ldap.
The security certificate encrypts conversation. The server always sends a digital certificate to confirm the server.
Characters that are illegal in ColdFusion can be used in LDAP attribute names. As a result, the cfldap
tag could create columns in the query result set whose names contain illegal characters and are, therefore, inaccessible in CFML. In ColdFusion, illegal characters are automatically mapped to the underscore character; therefore, column names in the query result set might not exactly match the names of the LDAP attributes.
For usage examples, see Developing ColdFusion MX Applications with CFML.
Example
<h3>cfldap Example</h3>
<p>Provides an interface to LDAP directory servers like BigFoot
(<a href = "http://www.bigfoot.com">http://www.bigfoot.com</A>).
<p>Enter a name (try your own name) and search a public LDAP resource.
<!--- If the server has been defined, run the query --->
<cfif IsDefined("form.server")>
<!--- check to see that there is a name listed --->
<cfif form.name is not "">
<!--- make the LDAP query --->
<cfldap server = "ldap.bigfoot.com"
action = "query"
name = "results"
start = "cn = #name#,c = US"
filter = "(cn = #name#)"
attributes = "cn,o,l,st,c,mail,telephonenumber"
sort = "cn ASC">
<!--- Display results --->
<center>
<table border = 0 cellspacing = 2 cellpadding = 2>
