Doesn't matter if it affects me or not. It affects all people in the East which are older than 26 - and that's quite a bunch. And not only that, it also affects all people who married in GDR times, who got qualification certificates then, all people which had been born then and want to marry nowadays.
If you live in the East these days, you got the lesser amount of problems as they are somehow accepted there (only case where it's not I heard is when you want to get married these days, but your birth certificate is from GDR times, you need to get a certificate of ancestry then in the town where you were born in).
But, I even had teachers telling me that - if they graduated in the GDR, they can work in their jobs when they keep being in the East, Bavaria e. g. wouldn't accept them. They'd regard them as invalid.
So I have already heard enough stories of other people with lesser degrees where qualifications were not recognized in the West German system.

Nice reunification, isn't it?
