Duplicated Serial Numbers (per CA)

sIssuer	SerialNumber	FriendlyName	DnsNameList	sSubject	revokedOn
internal-ca	2F	hsanchez	{hsanchez}	hsanchez
internal-ca	2F	city1	{city1}	city1	{revocados}
internal-ca	30	audit03	{audit03}	audit03	{revocados}
internal-ca	30	uaIntro	{uaIntro}	uaIntro
internal-ca	31	city04	{city04}	city04
internal-ca	31	uaDevice(2)	{uaDevice}	uaDevice
internal-ca	32	fperez	{fperez}	fperez
internal-ca	32	uaExit(2)	{uaExit}	uaExit

This is the last part of the result returned by the script: It shows duplicated SerialNumbers 2F, 30, 31 and 32 To avoid issues when some of this certs is revoked, you must revoked all them, and recreate new certs forevery user involved.

As example: The execution result shows that the "city1" and "audit03" certs are revoked in the "revocados" CRL. But due to the duplicity of SerialNumbers, the openVPN tunnel that uses "revocados" as CRL also will consider revoked the certs "hsanchez" and "uaIntro".

You can show certs that will expire in the next 90 days

$listaC | Where-Object {$_.NotAfter -le (Get-Date).AddDays(90)} | Select sIssuer, SerialNumber, FriendlyName, DnsNameList, sSubject, revokedOn | ft

---

Or the list of revoked Certs

$listaC | Where-Object {$_.revokedOn -ne $null} | Select sIssuer, SerialNumber, FriendlyName, DnsNameList, sSubject, revokedOn | ft

And everything you want :)
