Re: S/W request: add flag to LDAPSEARCH to identify version (ITS#971)

ident `which ldapsearch`

Though an option could be added to the OpenLDAP tools, this would
not solve your problem as the option name would be vendor specific.
That is, not all vendors will use the same flag to print version

For scripts, I don't recommend relying on detected vendor information.
I recommend specifying tool paths, tool names, and tool arguments
within the scripts (preferable with some localization appropriate
for your environment).
