MEG 7.x "fatal unknown ca" adding a Directory Service (exchange)

Jump to solution

Hi all

I have a problem adding a Directory Service in MEG 7.5 with MS Exchange 2013 using Secure LDAP or Use TLS options, but when I use no encrypted channel I don't have any problem.

I made a network capture and I can see this error: "FATAL unknown ca" after the exchange is sending the certificate over TLS 1.2 then the RST flag is sent.

Any ideas? Is TLS 1.2 supported in Exchange 2013? Can I import the exchange certificate to the MEG?

Thank you

Mauricio

There are two options to solve this.  The first is to add the Exchange certificate to the MEG.  This is done under Email --> Certificate Management --> Certificates --> CA Certificates.  Simply add the certificate or whatever CA chain may be used on Exchange.

The second method is to disable certificate verification for LDAP.  This is the check box at the bottom of Email --> Group Management --> Directory Services.  Unchecking the box will allow the the secure connection to work even if the certificate is not validated.
