Print the attribute CLI name instead of its 'real' name. The real name is usually the name of the corresponding LDAP attribute, which is confusing to the user.

                             This way we get:

Invalid 'login': blablabla

instead of:

Invalid 'uid': blablabla


Another example:

Invalid 'hostname': blablabla

instead of:

Invalid 'fqdn': blablabla

Subject: [PATCH 1/2] Fix reporting of errors when validating parameters.

Print the attribute CLI name instead of its 'real' name.
The real name is usually the name of the corresponding LDAP
attribute, which is confusing to the user.

This way we get:
Invalid 'login': blablabla
instead of:
Invalid 'uid': blablabla

Another example:
Invalid 'hostname': blablabla
instead of:
Invalid 'fqdn': blablabla
