func (*Client) ASExchange Uses

func (cl *Client) ASExchange(realm string, ASReq messages.ASReq, referral int) (messages.ASRep, error)

ASExchange performs an AS exchange for the client to retrieve a TGT.

func (*Client) ChangePasswd Uses

func (cl *Client) ChangePasswd(newPasswd string) (bool, error)

ChangePasswd changes the password of the client to the value provided.

func (*Client) Destroy Uses

func (cl *Client) Destroy()

func (*Client) Key Uses

func (cl *Client) Key(etype etype.EType, krberr *messages.KRBError) (types.EncryptionKey, error)

Key returns the client's encryption key for the specified encryption type. The key can be retrieved either from the keytab or generated from the client's password. If the client has both a keytab and a password defined the keytab is favoured as the source for the key A KRBError can be passed in the event the KDC returns one of type KDC_ERR_PREAUTH_REQUIRED and is required to derive the key for pre-authentication from the client's password. If a KRBError is not available, pass nil to this argument.
