What is LDAP? How PHP operates LDAP

how PHP operates LDAP
2.1 How PHP connects and shuts down with LDAP
$ds =ldap_connect ("ServerName")
ServerName is the name of the LDAP server,

Cases:
$ds =ldap_connect ("10.31.172.30:1000")
The return value is: TRUE or False

Close connection
Ldap_close ($DS);

2.2 How to search for user information in PHP

$ds =ldap_connect ("10.31.172.30:1000");
Connect to the server first
$justthese = Array ("CN", "UserPassword", "location");
Search for a parameter in a function that asks what information to return.
The above is returned to cn,userpassword,location, which requires lowercase
$SR =ldap_search ($ds, "O=jite", "cn=dom*", $justthese);
The first parameter opens the LDAP code
The second parameter most basic DN condition value, Example: "O=JITE,C=CN"
The third parameter, filter, is a Boolean condition, and its syntax can be found on a dirsdkpg.pdf file at Netscape station.
' O ' for organization name, ' CN ' for username, user name available wildcard ' * '
echo "DomAdmin surname has". Ldap_count_entries ($ds, $SR). "<p>";
Ldap_count_entries ($ds, $SR) returns the total number of records

$info = Ldap_get_entries ($ds, $SR);
Full return of LDAP data
echo "Data returns". $info [Count]. " Pen:<p> ";
for ($i =0; $i < $info [Count]; $i + +) {
echo "DN is:". $info [$i] [dn]. " <br> ";
Echo "CN is:". $info [$i] ["cn"][0]. " <br> "; Display user Name
echo "Email is:". $info [$i] ["Mail"][0]. " <p> "; Show mail
echo "Email is:". $info [$i] ["UserPassword"][0]. " <p> "; Display the encrypted password
}
2.3 Adding users
$ds =ldap_connect ("10.31.172.30:1000");
Connect to the server first
$r =ldap_bind ($ds, "Cn=domadmin,o=jite", "password");
Fasten an admin, have write permission
Cn=domadmin,o=jite order cannot be changed
$info ["cn"]= "AAA"; Must fill
$info ["UserPassword"]= "AAA";
$info ["Location"]= "Shanghai";
$info ["objectclass"] = "person"; Must fill in person for personal, also have server ...
Ldap_add ($ds, "cn=". $info ["cn"]. ", O=jite", $info);
Ldap_unbind ($DS);
Unbind
Ldap_close ($DS);
Close connection
2.4 Delete User
$ds =ldap_connect ("10.31.172.30:1000");
Connect to the server first
Ldap_bind ($ds, "Cn=domadmin,o=jite", "password");
Binding administrator, with permission to delete
$DN = "Cn=dingxf,o=jite";
Ldap_delete ($ds, $DN);
Delete User
Ldap_unbind ($DS);
Unbind
Ldap_close ($DS);
Close connection
2.5 Modify User Information
$ds =ldap_connect ("10.31.172.30:1000");
Connect to the server first
Ldap_bind ($ds, "Cn=domadmin,o=jite", "password");
Binding administrator, with modified permissions
$DN = "Cn=dingxf,o=jite";
User DN
$info ["UserPassword"]= "AAA"; The information to be modified, placed in the array variable
$info ["Location"]= "SHANGHAISDAF";

Ldap_modify ($ds, $DN, $info);
modifying functions
Ldap_unbind ($DS);
Unbind
Ldap_close ($DS);
Close connection
2.6 User logon authentication
$ds =ldap_connect ("10.31.172.30:1000");
Connect to the server first
if (Ldap_bind ($ds, "Cn=dingxf,o=jite", "DINGXF")) {
echo "Validate through";
}else{
echo "Validation does not pass";
}
Ldap_unbind ($DS);
Unbind
Ldap_close ($DS);
Close connection
