<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">They were used indirectly I think when you had some services configured for v2 only authentication support because the service didn't work with v2. For example nova->neutron was
v2 only for a while. I think all services are supporting v3 these days so that would no longer be necessary?<br>

Thanks,<br>

<div dir="ltr">When trusts were implemented, they were designed to work as an extension under the version 3 API. The implementation didn't prevent the use of a trust to authenticate against version 2.0, which was never officially documented in the v2.0 API
docs.
<div><br>
</div>
<div>The keystone team is curious if there is anyone creating trusts using v3 and then using them against version 2.0. If not, we'd like to remove/deprecate support for that case in v2.0. If so, then we'll have to add official documentation for trusts against
v2.0 and incorporate that case into fernet.</div>
