What's the difference between -h and -H ?

[Harry Rüter <harry_rueter@gmx.de>]

Hi,

i read the manpages of ldapwhoami (v2.1.4),
but i don't know what's the "real" difference 
between the -h and the -H option.

I show you, what makes me ask this question :

---snipp---
486dx66:~ # /usr/local/ldap/bin/ldapwhoami -h 486dx66.hrnet.de -p 5389
SASL/GSSAPI authentication started
SASL username: harry@HRNET.DE
SASL SSF: 56
SASL installing layers
dn:uid=harry,cn=hrnet.de,ou=ldap,o=myorganization,dc=hrnet,dc=de
Result: Success (0)
---snipp---

You see, it works fine, but -h is deprecated.

Now, the other way :

---snipp---
486dx66:~ # /usr/local/ldap/bin/ldapwhoami -H ldap://486dx66.hrnet.de -p 5389
SASL/GSSAPI authentication started
SASL username: harry@HRNET.DE
SASL SSF: 56
SASL installing layers
Result: Protocol error (2)
Additional info: unsupported extended operation
---snipp---

This doesn't work,
looking to the logfile of the server i see,
there's no connection, the error must be in ldapwhoami ..

Any suggestions to this behaviour ?

greets 

Harry
