|
|
* sanitizes a DN received from the LDAP server |
|
|
|
* |
|
|
|
* This is used and done to have a stable format of DNs that can be compared |
|
|
|
* and identified again. The input DN value is modified as following: |
|
|
|
* |
|
|
|
* 1) whitespaces after commas are removed |
|
|
|
* 2) the DN is turned to lower-case |
|
|
|
* 3) the DN is escaped according to RFC 2253 |
|
|
|
* |
|
|
|
* When a future DN is supposed to be used as a base parameter, it has to be |
|
|
|
* run through DNasBaseParameter() first, to recode \5c into a backslash |
|
|
|
* again, otherwise the search or read operation will fail with LDAP error |
|
|
|
* 32, NO_SUCH_OBJECT. Regular usage in LDAP filters requires the backslash |
|
|
|
* being escaped, however. |
|
|
|
* |
|
|
|
* Internally, DNs are stored in their sanitized form. |
|
|
|
* |
|
|
|
* @param array|string $dn the DN in question |
|
|
|
* @return array|string the sanitized DN |
