Indeed.
For the archives, here's the script I used:

#-------------------------------------------#
#!/usr/bin/perl
use MIME::Base64;
use strict;
my @md5 = split "",$ARGV[0];
my @res;
for (my $i = 0 ; $i < 32 ; $i+=2)
{
my $c = (((hex $md5[$i]) << 4) % 255) | (hex $md5[$i+1]);
$res[$i/2] = chr $c;
}
print "{MD5}".encode_base64(join "", @res);
#-------------------------------------------#

$ perl md5_sql2ldap.pl 5f4dcc3b5aa765d61d8327deb882cf99
{MD5}X03MO1qnZdYdgyfeuILPmQ==


Thanks.
