Functions

func AuthenticateUserDN

func AuthenticateUserDN(userDN string, password string, cfg *config.ConfigLDAP) (bool, error)

func CheckLDAPUser

func CheckLDAPUser(form PasswordForm, cfg *config.ConfigLDAP) (bool, error)

func CheckLocalUserIsAllowed

func CheckLocalUserIsAllowed(form PasswordForm, db *sqlx.DB, timeout time.Duration) (bool, error, error)

func CheckLocalUserPassword

func CheckLocalUserPassword(form PasswordForm, db *sqlx.DB, timeout time.Duration) (bool, error, error)

func CheckLocalUserToken

func CheckLocalUserToken(token string, db *sqlx.DB, timeout time.Duration) (bool, string, error)

CheckLocalUserToken checks the passed token against the records in the db for a match, up to a maximum duration of timeout.

func ConnectToLDAP

func ConnectToLDAP(cfg *config.ConfigLDAP) (*ldap.Conn, error)

func DerivePassword

func DerivePassword(password string) (string, error)

DerivePassword uses the https://godoc.org/golang.org/x/crypto/scrypt package to return an encrypted password that is compatible with the Perl CPAN library Crypt::ScryptKDF for backward compatibility to authenticate through the Perl API the same way. See: http://cpansearch.perl.org/src/MIK/Crypt-ScryptKDF-0.010/lib/Crypt/ScryptKDF.pm

func IsCommonPassword

func IsCommonPassword(pw string) bool

func IsGoodLoginPair

func IsGoodLoginPair(username string, password string) (bool, error)

func IsGoodPassword

func IsGoodPassword(password string) (bool, error)

func LoadPasswordBlacklist

func LoadPasswordBlacklist(filePath string) error

Expects a relative path from the traffic_ops directory

func LookupUserDN

func LookupUserDN(username string, cfg *config.ConfigLDAP) (string, bool, error)

func VerifySCRYPTPassword

func VerifySCRYPTPassword(password string, scryptPassword string) error

VerifySCRYPTPassword parses the original Derived Key (DK) from the SCRYPT password so that it can compare that with the password/scriptPassword param

Types

type CurrentUser

type CurrentUser struct {
	UserName     string         `json:"userName" db:"username"`
	ID           int            `json:"id" db:"id"`
	PrivLevel    int            `json:"privLevel" db:"priv_level"`
	TenantID     int            `json:"tenantId" db:"tenant_id"`
	Role         int            `json:"role" db:"role"`

}

func GetCurrentUser

func GetCurrentUser(ctx context.Context) (*CurrentUser, error)

func GetCurrentUserFromDB

func GetCurrentUserFromDB(DB *sqlx.DB, user string, timeout time.Duration) (CurrentUser, error, error, int)

GetCurrentUserFromDB - returns the id and privilege level of the given user along with the username, or -1 as the id, - as the userName and PrivLevelInvalid if the user doesn't exist, along with a user facing error, a system error to log, and an error code to return

type PasswordForm

type PasswordForm struct {
	Username string `json:"u"`
	Password string `json:"p"`
}

type SCRYPTComponents

type SCRYPTComponents struct {
	Algorithm string // The SCRYPT algorithm prefix

	R         int    // block size parameter (octets)
	P         int    // parallelization parameter (positive int)
	Salt      []byte // salt value
	SaltLen   int    // bytes to use as salt (octets)
	DK        []byte // derived key value
	DKLen     int    // length of the derived key (octets)
}

SCRYPTComponents the input parameters to the Scrypt encryption key format
