Re: LDAP script crash

[Daniel Miller <bonsaiviking () gmail com>]

Mike,

It's not immediately obvious what the problem is. I'd guess the ASN.1
parser expected an integer but was at the end of the data. If this is
reproducible, the output of this command would be helpful: nmap -d -p 389
--script ldap-rootdse --script-trace

This will show a packet trace of what inputs the script is getting. Then we
can manually trace it through to find what is wrong.
