I'm trying to import some of the available N1 plugins, namely for Linux and WebLogic 9. I have the following environment:
-FRESHLY installed Master Server with no plugins currently. (N1 SPS 6.0)
-OS is Red Hat Enterprise Linux AS release 4 (Nahant Update 6)
-MS is also a RA in a development environment using 'raw' connections
-install was performed as root with <n1user> as owner
I've tried through the Web Console and the following CLI with the same error:
my rough guess on this is that you used some other java and the java keystore in there doesn't have the proper CA certificates that were used to sign the plugin.
Try to use the java provided with N1SPS or extract proper CA certificates from other 6.0 installation that installed its own java and plug them into your java version.
Other problem might only be that the plugin you use was oddly signed (which I cannot explain and shouldn't be the case).
All in all there is a keytool or something like that in java directory which can print out signatures and certificates. Use it to fit the proper pair if you don't want to reinstall, otherwise the simplest is to reinstall and use java provided by SPS
