[TYPO3-dev] Cannot log in to backend on first attempt

[Ricardo Pereira]

	Dear Steffen,

	Thanks so very much for your reply.

	That's a good lead, but could you please be just a little bit more 
specific? What was wrong with cookie handling in your case?

	Thanks a million once again!!

	Cheers,

Ricardo
