func (*LDAPClientConfig) Connect 

func (l *LDAPClientConfig) Connect() (*ldap.Conn, error)

Connect returns an established LDAP connection, or an error if the connection could not be made (or successfully upgraded to TLS). If no error is returned, the caller is responsible for closing the connection

func (LDAPClientConfig) String added in v1.0.7 

func (l LDAPClientConfig) String() string

type LDAPQuery added in v1.0.7 

type LDAPQuery struct {
	// The DN of the branch of the directory where all searches should start from
	BaseDN string

	// The (optional) scope of the search. Defaults to the entire subtree if not set
	Scope Scope

	// The (optional) behavior of the search with regards to alisases. Defaults to always
	// dereferencing if not set
	DerefAliases DerefAliases

	// TimeLimit holds the limit of time in seconds that any request to the server can remain outstanding
	// before the wait for a response is given up. If this is 0, no client-side limit is imposed
	TimeLimit int

	// Filter is a valid LDAP search filter that retrieves all relevant entries from the LDAP server with the base DN
	Filter string
}

LDAPQuery encodes an LDAP query

func NewLDAPQuery added in v1.0.7
