You are lucky to get a reference tbh.
My current firm is inundated with them for past and future employees and so as a matter of policy gives out the bare essentials for everybody: Name, title and confirmation of employment dates and that's it.
Helpful & flexible a) costs and b) is potentially litigious.
I always give out full references to anyone who has worked for me if they are good. Not so good, then I err on the side of caution and give either minimum details or speak to people verablly. And I'm talking about people who lie, cheat and steal, not someone who came in late twice or came in hungover once.
A company I used to work for had that policy and it really annoyed me, because if my employer is only willing to give the bare bones then it makes me sound bad. I worked for them for two and a half years and was a good employee, the least they could do is give me a reference, even if they put a time limit on it, i.e. up to six months after leaving the company you get a proper reference, after that it's bare bones. Surely it wouldn't be that hard to draw up a few template letters, then just pick whichever one matched the person.
