I am not able to add a fba user to the site collection permissions. Someone can request access and I can approve the request, they receive the email with temp password and then change their password. But when I try to add the user to the site
collection permissions, the formsauth name comes up in the people picker but when you click Ok, I receive the "user does not exist or is not unique." It does take at least a minute for the peoplepicker to find the user. I am able to to
add AD users to the site with their windows authentication and do not get the error. I also tried adding the role to the site rather than the user and I get the same error. Any suggestions you can provide on this issue is much appreciated!
