When I was trying to add an entry like this using ldapadd(1):

dn: cn=name,dc=example,dc=com objectClass: inetOrgPerson cn: name sn: name mail:

slapd returned invalidAttributeSyntax(21) error on the mail (IA5 String) attribute. According to RFC4517, zero-length IA5 String should be allowed.

I note that while the directory service should allow such values, directory applications (e.g., client programs) and users should only provide values which make sense. An empty string (or a string consisting of just spaces) is not a valid email address and will likely lead to ill behavior. If the user represented by this entry has no email address, the mail attribute should have no value (as opposed to an empty value). But I digress...
