func ConfigFields

func ConfigFields() map[string]*framework.FieldSchema

ConfigFields returns all the config fields that can potentially be used by the LDAP client. Not all fields will be used by every integration.

func EscapeLDAPValue

func EscapeLDAPValue(input string) string

EscapeLDAPValue is exported because a plugin uses it outside this package.

type Client

type Client struct {
	Logger hclog.Logger
	LDAP   LDAP
}

func (*Client) DialLDAP

func (c *Client) DialLDAP(cfg *ConfigEntry) (Connection, error)

func (*Client) GetLdapGroups

func (c *Client) GetLdapGroups(cfg *ConfigEntry, conn Connection, userDN string, username string) ([]string, error)

* getLdapGroups queries LDAP and returns a slice describing the set of groups the authenticated user is a member of. * * If cfg.UseTokenGroups is true then the search is performed directly on the userDN. * The values of those attributes are converted to string SIDs, and then looked up to get ldap.Entry objects. * Otherwise, the search query is constructed according to cfg.GroupFilter, and run in context of cfg.GroupDN. * Groups will be resolved from the query results by following the attribute defined in cfg.GroupAttr. * * cfg.GroupFilter is a go template and is compiled with the following context: [UserDN, Username] * UserDN - The DN of the authenticated user * Username - The Username of the authenticated user * * Example: * cfg.GroupFilter = "(&(objectClass=group)(member:1.2.840.113556.1.4.1941:={{.UserDN}}))" * cfg.GroupDN = "OU=Groups,DC=myorg,DC=com" * cfg.GroupAttr = "cn" * * NOTE - If cfg.GroupFilter is empty, no query is performed and an empty result slice is returned. *

func (*Client) GetUserBindDN

func (c *Client) GetUserBindDN(cfg *ConfigEntry, conn Connection, username string) (string, error)

* Discover and return the bind string for the user attempting to authenticate. * This is handled in one of several ways: * * 1. If DiscoverDN is set, the user object will be searched for using userdn (base search path) * and userattr (the attribute that maps to the provided username). * The bind will either be anonymous or use binddn and bindpassword if they were provided. * 2. If upndomain is set, the user dn is constructed as 'username@upndomain'. See https://msdn.microsoft.com/en-us/library/cc223499.aspx *

func (*Client) GetUserDN

func (c *Client) GetUserDN(cfg *ConfigEntry, conn Connection, bindDN string) (string, error)

* Returns the DN of the object representing the authenticated user.

type ConfigEntry

type ConfigEntry struct {
	Url            string `json:"url"`
	UserDN         string `json:"userdn"`
	GroupDN        string `json:"groupdn"`
	GroupFilter    string `json:"groupfilter"`
	GroupAttr      string `json:"groupattr"`
	UPNDomain      string `json:"upndomain"`
	UserAttr       string `json:"userattr"`
	Certificate    string `json:"certificate"`
	InsecureTLS    bool   `json:"insecure_tls"`
	StartTLS       bool   `json:"starttls"`
	BindDN         string `json:"binddn"`
	BindPassword   string `json:"bindpass"`
	DenyNullBind   bool   `json:"deny_null_bind"`
	DiscoverDN     bool   `json:"discoverdn"`
	TLSMinVersion  string `json:"tls_min_version"`
	TLSMaxVersion  string `json:"tls_max_version"`
	UseTokenGroups bool   `json:"use_token_groups"`

	// This json tag deviates from snake case because there was a past issue
	// where the tag was being ignored, causing it to be jsonified as "CaseSensitiveNames".
	// To continue reading in users' previously stored values,
	// we chose to carry that forward.
	CaseSensitiveNames *bool `json:"CaseSensitiveNames,omitempty"`
}

func NewConfigEntry

func NewConfigEntry(existing *ConfigEntry, d *framework.FieldData) (*ConfigEntry, error)

* Creates and initializes a ConfigEntry object with its default values, * as specified by the passed schema.

func (*ConfigEntry) Map

func (c *ConfigEntry) Map() map[string]interface{}

func (*ConfigEntry) PasswordlessMap

func (c *ConfigEntry) PasswordlessMap() map[string]interface{}

func (*ConfigEntry) Validate

func (c *ConfigEntry) Validate() error

type Connection

type Connection interface {
	Bind(username, password string) error
	Close()
	Modify(modifyRequest *ldap.ModifyRequest) error
	Search(searchRequest *ldap.SearchRequest) (*ldap.SearchResult, error)
	StartTLS(config *tls.Config) error
	UnauthenticatedBind(username string) error
}

Connection provides the functionality of an LDAP connection, but through an interface.

type LDAP

type LDAP interface {
	Dial(network, addr string) (Connection, error)
	DialTLS(network, addr string, config *tls.Config) (Connection, error)
}

LDAP provides ldap functionality, but through an interface rather than statically. This allows faking it for tests.

func NewLDAP

func NewLDAP() LDAP
