Not sure if this has been posted here before (I searched but like many other forums, the search function is useless), but I have encountered an incredibly annoying glitch during the Battle for Solitude quest. When arriving at solitude and listening to Ulfric Stormcloak preparing the troops for battle, they all enter the city through the main gate but for some reason when I go up to it to enter, it says it is locked and requires a key. Not sure how I'm supposed to proceed because by the looks of things, Solitude is going to be locked from entry indefinitely for me (the icon for Fast-Travel has been removed while the quest is in progress.) Seriously? What am I supposed to do here?

You sure you searched? There's another thread with almost the exact same title right here on the first page!

I did and it didn't show up. They are two separate bugs.

Found the solution. When I first tried to get in I rode up on Shadowmere (the horse from the Dark Brotherhood quest line). Apparently this made Ulfric skip his stupid little speech and run through the door ahead of everyone else, causing the door to say locked. I can imagine that if one were to try and open the door before he finished speaking, it would say the same thing. Nice Bethesda, real nice.
