The following methods of authentication are deprecated, and supported for backwards-compatibility reasons only. It is strongly recommended to update MantisBT installations relying on these to use Section 8.1, “Standard Authentication” instead.
Deprecated values for $g_login_method:
CRYPT
CRYPT_FULL_SALT
PLAIN
With CRYPT-based methods, the password's length is limited as per Standard Authentication. With PLAIN, its size is restricted as for Basic Authentication.
