ColdFusion 8: Added the ability to use a comma as a delimiter when specifying a list of variables in the returnAsBinary attribute, for example, returnAsBinary="objectGUID,objectSID". Previously, the allowed delimiter was a space.
ColdFusion MX 7: Added the returnAsBinary attribute. Added SSL V2 client based authentication; this means that ColdFusion supports the CFSSL_CLIENT_AUTH option. If CFSSL_CLIENT_AUTH is selected, ColdFusion assumes that the first certificate in the cacerts (or the certificate database) contains the Client Certificate.
ColdFusion MX:
Attribute |
Req/Opt |
Default |
Description |
---|---|---|---|
action |
Required |
query |
|
server |
Required |
|
Host name or IP address of LDAP server. |
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. |
delimiter |
Optional |
; (semicolon) |
Separator between attribute name-value pairs. Use this attribute if either of these situations exist:
Used by query, add, and modify actions, and by cfldap to output multivalue attributes. For example, if $ (dollar sign), you could specify "cn = Double Tree Inn$street = 1111 Elm; Suite 100, where the semicolon is part of the street value. |
dn |
Required if action = "Add", "Modify", "ModifyDN", or "delete" |
|
Distinguished name, for update action, for example, |
filter |
Optional |
"objectclass = *" |
Search criteria for action = "query". List attributes in the form: "(attribute operator value)" For example: "(sn = Smith)" |
maxRows |
Optional |
|
Maximum number of entries for LDAP queries. |
modifyType |
Optional |
replace |
How to process an attribute in a multivalue list:
You cannot add an attribute that is already present or that is empty. |
name |
Required if action = "Query" |
|
Name of LDAP query. The tag validates the value. |
password |
Required if secure = "CFSSL_BASIC" |
|
Password that corresponds to user name. If secure = "CFSSL_BASIC", V2 encrypts the password before transmission. |
port |
Optional |
389 |
Port. |
rebind |
Optional |
no |
|
referral |
Optional |
|
Integer. Number of hops allowed in a referral. A value of 0 disables referred addresses for LDAP; no data is returned. |
returnAsBinary |
Optional |
A space-delimited list of columns that are to be returned as binary values. |
|
scope |
Optional |
oneLevel |
Scope of search, from entry specified in start attribute for action = "Query".
|
secure |
Optional |
|
Security to employ, and required information. One of the following:
|
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. |
sort |
Optional |
|
Attribute(s) by which to sort query results. Use a comma delimiter. |
sortControl |
Optional |
asc |
You can enter a combination of sort types; for example, sortControl = "nocase, asc". |
start |
Required if action = "Query" |
|
Distinguished name of entry to be used to start a search. |
startRow |
Optional |
1 |
Used with action = "query". First row of LDAP query to insert into a ColdFusion query. |
timeout |
Optional |
60000 |
Maximum length of time, in milliseconds, to wait for LDAP processing. |
username |
Required if secure = "CFSSL_BASIC" |
(anonymous) |
User ID. |
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 |
If you use the security="CFSSL_BASIC" option, ColdFusion determines whether to trust the server by comparing the server's certificate with the information in the jre/lib/security/cacerts keystore of the JRE used by ColdFusion. The ColdFusion default cacerts file contains information about many certificate granting authorities. If you must update the file with additional information, you can use the keytool utility in the ColdFusion jre/bin directory to import certificates that are in X.509 format. For example, enter the following:
keytool -import -keystore cacerts -alias ldap -file ldap.crt -keypass bl19mq
Then restart ColdFusion. The keytool utility initial keypass password is "change it". For more information on using the keytool utility, see the Sun JDK documentation.
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 the ColdFusion Developer's Guide.
