Functions

func FixInvalidLocales 

func FixInvalidLocales(cfg *model.Config) bool

FixInvalidLocales checks and corrects the given config for invalid locale-related settings.

Ideally, this function would be completely internal, but it's currently exposed to allow the cli to test the config change before allowing the save.

func GenerateClientConfig 

func GenerateClientConfig(c *model.Config, diagnosticID string, license *model.License) map[string]string

GenerateClientConfig renders the given configuration for a client.

func GenerateLimitedClientConfig

func Merge 

func Merge(cfg *model.Config, patch *model.Config, mergeConfig *utils.MergeConfig) (*model.Config, error)

func Migrate 

func Migrate(from, to string) error

Migrate migrates SAML keys, certificates, and other config files from one store to another given their data source names.
