VERSION
version 3.4.0.2SYNOPSIS
use CipUX::Storage;
DESCRIPTION
The CipUX Storage abstraction layer is a generic abstract class, which can be used to access LDAP servers via Perl by issuing simple actions and via shell command line interface. It was tested with openLDAP version 3. The layer is capable of operating on different sets of LDAP nodes. A set of nodes might be defined by an LDAP objectClass or LDAP attribute. Example: cipuxAccount or posixAccount. The number of objects inside a set might be ranged from one to many. The abstraction layer performs a method on a set of nodes. Valid methods are: 'get', 'set', 'get-all', 'set-all' on LDAP attribute values and 'add', 'delete', 'rename' on LDAP nodes.It provides the functions get_value, set_value to modify LDAP attribute values. The function add_node, delete_node and rename_node for adding, deleting and renaming LDAP objects.
SUBROUTINES/METHODS
The following functions will be exported by CipUX::Storage.BUILD
This is the constructor, see new.
use CipUX::Storage; use base qw(CipUX::Storage); my $storage = CipUX::Storage->new();
DEMOLISH
This is the destructor.get_value
The get_value queries the LDAP and returns one ore more values depending on the parameter 'scope'.Syntax:
eval {
my $object = 'ckuelker';
my $attribute = 'cipuxFirstname';
my $type = 'all_user_node';
$value_hr = $ldap->get_value({
scope=>'one',
type=>$type,
obj=>$object,
attr_ar=>[$attribute]
});
} or croak "ERROR: can't get value: $@!" if $@;
returns one value:
%$ret_hr = (
'ckuelker' => {
'cipuxFirstname' => ['Christian'],
}
);
eval {
my $object = '';
my $attribute = 'cipuxFirstname';
my $type = 'all_user_node';
$value_hr = $ldap->get_value({
scope=>'all',
type=>$type,
obj=>$object,
attr_ar=>[$attribute]
});
} or croak "ERROR: can't get value: $@!" if $@;
%$ret_hr = (
'ckuelker' => {
'cipuxFirstname' => ['Christian'],
'cipuxLastname' => ['Kuelker'],
},
'xoswald' => {
'cipuxFirstname' => ['Xavier'],
'cipuxLastname' => ['Oswald'],
},
);
Return values
%ret = (
'ckuelker' => {
'cipuxFirstname' => ['Christian'],
'cipuxLastname' => ['Kuelker'],
}
set_value
Sets a value for a given object in the LDAP database.
my $rslt = set_value( {
obj=>$obj,
attr_ar=>$attr_ar,
changes=>$changes,
scope=>$scope,
escope=>$escope,
type=>$type
} ;
obj: object
attr_ar: reference to an array of LDAP attributes and values
changes:
scope: 'one|all' set/modify value
escope: 'one|all|none' erase scope
type:
Modify Syntax
my $msg = $ldap->modify( $dn,
changes => [
# add sn=Baggins
add => [ sn => 'Baggins' ],
# delete all fax numbers
delete => [ faxNumber => []],
# delete phone number 911
delete => [ telephoneNumber => ['911']],
# change email address
replace => [ mail => '[email protected]']
]
);
add_node
Adds an LDAP node to the LDAP database.
my $rslt = $cipux->add_node({obj=>$obj, type=>$type, attr_hr=>$attr_hr});
obj : The object to be added
type: kind of object to be added
attr_hr: Hash reference with 'ldap_attribute=>value' structure
$rslt: is the reslult from Net::LDAP add
delete_node
Deletes an LDAP node from the LDAP database.
my $rslt = $cipux->delete_node( { obj=>$obj, type=>$type } );
obj : The object to be added
type: kind of object to be added
$rslt: is the result from Net::LDAP delete
rename_node
Rename an LDAP node of the LDAP database.
my $rslt = $cipux->rename_node({obj=>$obj, type=>$type, value=>$value });
obj : The object to be added
type: kind of object to be added
value: The new name
$rslt: is the result from Net::LDAP rename
_ldap_start
Binds to the LDAP server.
my %access = ();
$access_cfg{ident $self}->{uri} = 'ldap://localhost';
$access_cfg{ident $self}->{bind_dn} = 'cn=admin,dc=nodomain';
$access_cfg{ident $self}->{password} = 'secret';
my $ldap = $cipux->_ldap_start();
$ldap: is the LDAP Perl object returned from Net::LDAP.
_ldap_start
Unbinds from the LDAP server.
my $msg = $cipux->_ldap_end( { ldap=>$ldap} );
$msg: is the message returned from Net::LDAP.
list_storage_type
Lists all CipUX LDAP nodes entities, sorted.
my $list_ar = $cipux->list_type( { ldap=>$ldap} );
$list_ar: reference to an array of sorted CipUX LDAP entities.
_ldap_struct
Parses cipux-storage.perl with for object, type, filter of a given scope. It also performs some simple validation of that file.
my $ldap_structure_hr = $cipux->_ldap_struct( {
obj=>$obj,
type=>$type,
scope=>$scope,
filter=>$filter
});
$ldap_structure_hr: returns a structure hash reference
oid_number_supremum
Searches the storage database for uidNumber and gidNumber. It returns the one number above the largest number or the minimum number in the number range for users and groups.To perform the search it uses get_value (the storage layer itself).
get_sid
Retrieve sambaSID and return it if successfulConfiguration files
cipux-access.ini
The CipUX access configuration has the following entries:
[ldap] uri = ldaps://ldap bind_dn = cn=cipuxroot,dc=nodomain base_dn = ou=CipUX,dc=nodomain password = secret system = debian customer =
cipux_storage.perl
The storage structure configuration might look like this:
$cfg = {
'structure' => {
all_group_node => {
desc => 'access to all CN group objects',
struc_rdn => 'ou=Group',
dn_attr => 'cn',
filter => '(cn=?)',
},
all_user_node => {
desc => 'access to all system UID objects',
struc_rdn => 'ou=User',
dn_attr => 'uid',
filter => '(uid=?)',
},
course_group_node => {
desc => 'access to all system GID objects',
struc_rdn => 'ou=Group',
dn_attr => 'cn',
filter => '&(cn=?)(groupType=public)',
},
},
}
