slapd -d ? emits the incorrect numeric value for LDAP_DEBUG_ANY on x86_64:

$ slapd -d \?
Installed log subsystems:
        Any                            (18446744073709551615)
[...]
$ slapd -d 18446744073709551615
unrecognized log level "18446744073709551615"

Debug levels are always treated as type int, which is four bytes on Linux
x86_64. loglevel_print() in servers/slapd/bconfig.c seems to blame, since it's
using a long-typed format (%lu) instead of an unsigned int-typed one (%u).
