Hmm, I'd rather consider this to be a bug in Integer syntax implementation of slapd. IMO slapd SHOULD (and easily could) normalize integer attribute values with leading zeros.

Nope. It may be a bug in the Integer syntax definition in LDAP, but slapd just implements the spec. The Integer syntax is defined in RFC4517 as
Integer = ( HYPHEN LDIGIT *DIGIT ) / number
So there is an explicit distinction between leading digits (LDIGIT) and arbitrary digits (DIGIT). And LDIGIT is defined in RFC4512 to explicitly exclude zero, i.e., leading zeroes are explicitly disallowed.

So - to comply with the spec, clients should not be generating integer values with leading zeroes. If you don't like this, you have to change the LDAP spec first.
