* Run a ldap search query
|

986 |
*
|

987 |
* Search is used to query the ldap-database.
|
|
|
988 |
* $base and $filter may be ommitted. The one from config will
|
|
|
989 |
* then be used. $base is either a DN-string or an Net_LDAP2_Entry
|
|
|
990 |
* object in which case its DN willb e used.
|
|
|
991 |
*
|
|
|
992 |
* Params may contain:
|
|
|
993 |
*
|
|
|
994 |
* scope: The scope which will be used for searching
|
|
|
995 |
* base - Just one entry
|
|
|
996 |
* sub - The whole tree
|
|
|
997 |
* one - Immediately below $base
|
|
|
998 |
* sizelimit: Limit the number of entries returned (default: 0 = unlimited),
|
|
|
999 |
* timelimit: Limit the time spent for searching (default: 0 = unlimited),
|
|
|
1000 |
* attrsonly: If true, the search will only return the attribute names,
|
|
|
1001 |
* attributes: Array of attribute names, which the entry should contain.
|

1002 |
* It is good practice to limit this to just the ones you need.

* [NOT IMPLEMENTED]
|

* deref: By default aliases are dereferenced to locate the base object for the search, but not when
|
|
|
1005 |
* searching subordinates of the base object. This may be changed by specifying one of the
|
|
|
1006 |
* following values:
|
|
|
1007 |
*
|
|
|
1008 |
* never - Do not dereference aliases in searching or in locating the base object of the search.
|
|

1009 |
* search - Dereference aliases in subordinates of the base object in searching, but not in
|
|

1589 |
* the schema information on disk, so the schema is not fetched
|
|

1590 |

|

* to store the schema in a linux tmpfs which results in the schema

1601 |
