Active Directory - Exchange - Wildcard SSL

We decide that to buy a wild card SSL for *
but our minds get in trouble with texts :)
Some of the web sites tell
LDAPS (Lightweight Directory Access Protocol) does not support wildcards.
Active Directory does not support wildcards.

i just want to know that should we use a wildcard ssl on all servers connected to the Active directory server i mean on

active directory server
exchange server
web server
san server

should i use one wildcard ssl  ?
do i need to check for some specific point for that ?
is there any resourse that i should follow to install on active directory server ?

You can use wild card.
Bur for Exchange recommended is UC/SAN certificate.
Not sure about AD

so it is not reliable to use one wildcard for all system ?
I mean what is your advice applying different certificates to servers instead of one wildcard ?
UC/SAN cert for exchange maybe for the others wilidcard ?
Does uc/san support multi subdomain like autodiscover.domain mail.domain ...etc ?
Seth SimmonsSr. Systems AdministratorCommented:
i personally would only use a wildcard certificate if you plan to use for multiple public-facing systems
for example, you could use for exchange but also for other web servers in the same domain
however, if you only have exchange, i would use a SAN cert as suggested
for internal systems only (AD, etc.) i would build an internal CA server which is much easier to setup for those systems
spending extra money on a wildcard cert for use on one system isn't worth the money

that link you referenced is outdated; other applications (like lync) now do support wildcard cert

we have a public system. And using
Active directory

Is there any thing that we need to do before generating certificate from the authority that we need to very very specially control  ?
FireBallITAuthor Commented:
or do we need to check for spesific feature on wild card ssl ?
Seth SimmonsSr. Systems AdministratorCommented:
in that case a wildcard cert would work for you for sharepoint, exchange and lync
not sure what you mean by special long as the domain matches the public domain you are using, should be fine
i had done this at one place where we used it for exchange and customer web sites that required ssl
just added the domain name and it worked for all

while activating Wildcard SSL it asks for cer.
Where should i get the cer for the general system on a topology like that ?
Seth SimmonsSr. Systems AdministratorCommented:
not sure what you mean
are you in the process of purchasing it or installing it somewhere?
FireBallITAuthor Commented:
we have bought now it asked for CSR but i am not sure where to create CSR, i never worked with wildcard ssl before.
There are many places to generate CSR but for a complete domain where is the best place to generate CSR :)
FireBallITAuthor Commented:

what should be the pointed places
Seth SimmonsSr. Systems AdministratorCommented:
csr is generated by the application; for example when you create a request from the exchange console then copy and paste the csr
who are you getting the cert from?
they typically will have instructions on how to do it
i've only used godaddy for wildcart cert though shouldn't be too different
FireBallITAuthor Commented:
who are you getting the cert from?

tehere are some opstions at the bottom but could not decide what to write to san part and select from bottom
Seth SimmonsSr. Systems AdministratorCommented:
which one did you select? seems you can choose different vendors from there
this provides the documents for the various ones

Where can I find instructions on how to generate a CSR?
