Constructor Detail

LDAPConstraints

public LDAPConstraints()

Constructs an LDAPConstraints object that specifies the default set of constraints.

LDAPConstraints

public LDAPConstraints(int msLimit,
                       boolean doReferrals,
                       LDAPRebind rebind_proc,
                       int hop_limit)

Constructs a new LDAPConstraints object and allows you to specify the constraints in that object.

Parameters:

msLimit - maximum time in milliseconds to wait for results (0 by default, which means that there is no maximum time limit)

doReferrals - specify true to follow referrals automatically, or False to throw an LDAPReferralException error if the server sends back a referral (False by default)

rebind_proc - specifies the object that implements the LDAPRebind interface (you need to define this class). The object will be used when the client follows referrals automatically. The object provides the client with a method for getting the distinguished name and password used to authenticate to another LDAP server during a referral. (This field is null by default.)

hop_limit - maximum number of referrals to follow in a sequence when attempting to resolve a request

See Also:

LDAPConnection.setOption(int, java.lang.Object)

LDAPConstraints

public LDAPConstraints(int msLimit,
                       boolean doReferrals,
                       LDAPBind bind_proc,
                       int hop_limit)

Constructs a new LDAPConstraints object and allows you to specify the constraints in that object.

Parameters:

msLimit - Mmaximum time in milliseconds to wait for results (0 by default, which means that there is no maximum time limit)

doReferrals - specify true to follow referrals automatically, or False to throw an LDAPReferralException error if the server sends back a referral (False by default)

bind_proc - specifies the object that implements the LDAPBind interface (you need to define this class). The object will be used to authenticate to the server on referrals. (This field is null by default.)

hop_limit - maximum number of referrals to follow in a sequence when attempting to resolve a request

See Also:

LDAPConnection.setOption(int, java.lang.Object)

Method Detail

getTimeLimit

public int getTimeLimit()

Returns the maximum number of milliseconds to wait for any operation under these constraints. If 0, there is no maximum time limit on waiting for the operation results.

Returns:

maximum number of milliseconds to wait for operation results.

getReferrals

public boolean getReferrals()

Specifies whether nor not referrals are followed automatically. Returns true if referrals are to be followed automatically, or false if referrals throw an LDAPReferralException.

Returns:

true if referrals are followed automatically, false if referrals throw an LDAPReferralException.

getBindProc

public LDAPBind getBindProc()

Returns the object that provides the mechanism for authenticating to the server on referrals. This object must implement the LDAPBind interface.

Returns:

object to use to authenticate to the server on referrals.

See Also:

LDAPBind

getRebindProc

public LDAPRebind getRebindProc()

Returns the object that provides the method for getting authentication information. This object must implement the LDAPRebind interface.

Returns:

object to use to obtain information for authenticating to other LDAP servers during referrals.

See Also:

LDAPRebind, LDAPRebindAuth

getHopLimit

public int getHopLimit()

Returns the maximum number of hops to follow during a referral.

Returns:

maximum number of hops to follow during a referral.

getClientControls

public LDAPControl[] getClientControls()

Returns any client controls to be applied by the client to LDAP operations.

Returns:

client controls for the client to apply to LDAP operations.

See Also:

LDAPControl, LDAPConnection.getOption(int), LDAPConnection.setOption(int, java.lang.Object)

getServerControls

public LDAPControl[] getServerControls()

Returns any server controls to be applied by the server to LDAP operations.

Returns:

server controls for the server to apply to LDAP operations.

See Also:

LDAPControl, LDAPConnection.getOption(int), LDAPConnection.setOption(int, java.lang.Object)

setTimeLimit

public void setTimeLimit(int msLimit)

Sets the maximum number of milliseconds to wait for any operation under these constraints. If 0, there is no maximum time limit on waiting for the operation results. If the time limit is exceeded, an LDAPException with the result code LDAPException.TIME_LIMIT is thrown.

Parameters:

msLimit - Maximum number of milliseconds to wait for operation results (0 by default, which means that there is no maximum time limit.)

See Also:

LDAPException.LDAP_TIMEOUT

setReferrals

public void setReferrals(boolean doReferrals)

Specifies whether or not referrals are followed automatically. Specify true if referrals are to be followed automatically, or false if referrals are to throw an LDAPReferralException. (By default, this is set to false.)

If you set this to true, you need to create an object of this class that implements either the LDAPRebind or LDAPBind interface. The LDAPRebind object identifies the method for retrieving authentication information which will be used when connecting to other LDAP servers during referrals. This object should be passed to the setRebindProc method. Alternatively, the LDAPBind object identifies an authentication mechanism to be used instead of the default authentication mechanism when following referrals. This object should be passed to the setBindProc method.

Parameters:

doReferrals - set to true if referrals should be followed automatically, or False if referrals should throw an LDAPReferralException

See Also:

LDAPBind, LDAPRebind, LDAPRebindAuth

setBindProc

public void setBindProc(LDAPBind bind_proc)

Sets the object that provides the mechanism for authenticating to the server on referrals. This object must implement the LDAPBind interface.(By default, this is null.) This method sets the LDAPRebind object to null for this constraint.

Parameters:

bind_proc - object to use to authenticate to the server on referrals

See Also:

LDAPBind

setRebindProc

public void setRebindProc(LDAPRebind rebind_proc)

Specifies the object that provides the method for getting authentication information. This object must belong to a class that implements the LDAPRebind interface. (By default, this is null.) This method sets the LDAPBind object to null for this constraint.

Parameters:

rebind_proc - object to use to obtain information for authenticating to other LDAP servers during referrals

setHopLimit

public void setHopLimit(int hop_limit)

Sets maximum number of hops to follow in sequence during a referral. (By default, this is 5.)

Parameters:

hop_limit - maximum number of hops to follow during a referral

setClientControls

public void setClientControls(LDAPControl control)

Sets a client control for LDAP operations.

Parameters:

control - client control for LDAP operations

See Also:
