to maintain a textual representation of the credentials that the
plug-in expects to obtain for the selected identity. It can,
alternatively, be used to indicate the state of the credentials
type in respect to the selected identity (for example, whether
the credentials type is disabled for the identity and why).
This text is not visible when the new credentials window is in
basic mode, but it is visible when the window is in advanced
mode. The following image shows the expanded new credentials
window including the credentials text from a several plug-ins:

Therefore, the list will contain at most one identity. It is
possible for the list to be empty (for example, if the user
hasn't selected an identity yet).
When handling this notification, the plug-in should check the \c
n_identities member of the ::khui_new_creds structure to see
whether there are any identities selected. This value would be
either zero or one. If it is non-zero, then a handle to the
selected identity will be in \c khui_new_creds::identities[0].
Plug-ins typically use this notfication to load identity
specific settings when a new identity is selected.
