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.
