That is not an exception to the rule, and I am not aware thatb there 
are any exceptions to this one.  The rule is that "an" is used before 
words beginning with a vowel *sound*, and "a" is used before words 
beginning with a consonant *sound*.   "User" begins with the sound of 
the consonant "y": a user; "hour" begins with the sound of the vowel 
"ah": an hour.
