!!! Overview
[{$pagename}] allows an administrator to view and perform diagnostic functions for the [Security Domain Infrastructure] [SDI Key](s) within a tree and to ensure that all [NcpServers] are synchronized with constant keys.

[{$pagename}] is provided as SDIDIAG.NLM for [NetWare] and SDIDIAG.EXE which can be run from [Microsoft Windows] against any other platform.

!! Where to Find [{$pagename}]
Seems it is very difficult to find anything on [Micro Focus] site anymore so here is the last location we could find [{$pagename}]: \\[SDIDiag 3.0|https://download.novell.com/protected/Summary.jsp?buildid=kiPY4RZsMew~|target='_blank']

The page at the top shows: Restriction Status: Restricted but then at the bottom it says: Distribution Type: Public (So who knows)

There is also a [RPM] (sdidiag.x86_64.rpm) for [Linux] and sdidiag64.exe for [Windows Server] both require [eDirectory] binaries be installed on the local host.

SDIDiag is the [Security Domain Infrastructure] Diagnostic and repair utility.
SDIDiag allows an administrator to view the various [SDI Key]s within a tree and to ensure that all servers are synchronized with constant keys. 

By default SDIDiag 3.0 has been tested and works with [eDirectory] 9 and 8.8 SP8. For earlier versions of eDirectory and for 32-bit versions please find SDIdiag 2.2 also on the Patch site.

!! [Example] SDIDiag 3.0 
In older versions the past you could change the port by:
Server IP Addr (:port)  :

%%warning
SDIDiag 3.0 RPM (sdidiag.x86_64.rpm) we could not change the [port] to something other than 524.
