Hi cas-users,

I'm currently upgrading a CAS instance from version 3.3.5 to 3.4.2.1, and have noticed a change to the format of the login tickets (ie, the hidden field "lt" in the login form which is used to prevent replaying credentials).

Previously they were nice and long (76 characters) and looked pretty random. But since upgrading I'm getting very short login tickets generated, and they always follow the same pattern: "e1s1", "e2s1", "e3s1" etc. The CAS protocol states they should be "probabilistically unique" which these are not.

I'm not familiar with the spring framework used by CAS, so I'm not sure sure where to start looking. I have verified this happens with an uncustomised maven build of 3.4.2.1. Is this intentional, or a bug?

Cheers,
Tim
