Our certificates are signed by Terena, it has the following chain: Root -> intermediate Cert -> intermediate Cert -> Server cert

Supplying the chain works fine with apache and webaccess (look here: https://mail.tgm.ac.at), but not for my gwia.

I followed this guide and made a file with
-----BEGIN CERTIFICATE-----
server certificate text
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
intermediate certificate text
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
intermediate certificate text
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
trusted root text
-----END CERTIFICATE-----

When I configure my gwia to use this file I get the error
Code:
208 Warning - Failure in SSL startup (8920).
When I enter just my server certificate gwia starts up just fine - but obviously the clients are complaining about incomplete chains.

I do not have any extra <cr><lf>, as was hinted in an earlier post.

I'm at my wits end - does anybody have an idea?
