// DESCRIPTION
|

|
|
//
|
||
|
|
// This class allows multiple clients to share a single LDAP connection.
|
||
|
|
// The connection is reference counted and will be automatically unbound
|
||
|
|
// when the last reference is released. It also contains a disabled flag
|
||
|
|
// that any client can use to indicate that the connection has gone bad.
