The 32-bit value 4294967295 for LDAP_DEBUG_ANY is also rejected. lutil_atoix() declares i as type long and tries to check for overflow(?) with this cast:

if ( (long)(int)i != i ) {

which always fails in this case on x86_64. lutil_atoux() might be the more appropriate choice here.

str2loglevel() seems to behave correctly by virtue of verb_to_mask() returning an index into loglevel_ops, but I haven't checked extensively. loglevel_init(), however, does specify a hardcoded -1 for the Any level instead of LDAP_DEBUG_ANY.
