If we allowed tenant-uniqueness for usernames, then in order to log in and guarantee uniqueness so we could authZ someone, we would need to know the tenant up front as well. Current systems (like logging in to the horizon dashboard) *do not* require that.</div><div><br></div><div>-joe</div><div><br><div><div>On Aug 14, 2012, at 4:55 PM, Naveen Joy (najoy) <<a href="mailto:najoy@cisco.com">najoy@cisco.com</a>> wrote:</div><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">It’s valid for the same username to exist across multiple tenants and should be only unique for a tenant.
