Subject: Make availble a list of alternative aut methods
X-Git-Tag: v1.0.0~41
X-Git-Url: http://git.cascardo.info/?p=cascardo%2Fipsilon.git;a=commitdiff_plain;h=c42a8dc97e454f66b5e3d1a99b259e38e8496f85

Make availble a list of alternative aut methods

In the form case there is no way to automatically fallback to
other auth methods or even repeat transparent methods.
Add a simple list of alternative auth methods under the description
box so that the user can easily switch back and forth between them
if desired.
