You're correct.http://blog.apastyle.org/apastyle/2012/04/using-a-or-an-with-acronyms-and-abbreviations.html
It is pronounced ell-double-ewe-bee so is fine to use 'an'. I'm probably wrong but that is how I was taught in English GCSE - if the acronym begins with a consonant whose sound begins with a vowel, use 'an'.
