通过profile:本地登录掩码，可以做到一定程度的登录页面个性化

Set the profile option Local Login Mask (FND_SSO_LOCAL_LOGIN_MASK).
(This profile option is provided by SSO Pre-Req for Application Products- Rollup C,D and E)

For the Login page to show one of more of these optional attributes, just add
the numeric values of all desired attributes and set the value of the profile
option to that value.
USERNAME_HINT       = 01
PASSWORD_HINT       = 02
CANCEL_BUTTON       = 04
FORGOT_PASSWORD_URL = 08
REGISTER_URL        = 16
LANGUAGE_IMAGES     = 32
SARBANES_OXLEY_TEXT = 64

So, for example to show PASSWORD_HINT and FORGOT_PASSWORD_URL only, set the
profile option to 10 (02+08). To show just the LANGUAGE_IMAGES set the value
to 32, which is the default.
