Finally I was able to dig myself out of troubles. Below is something I would like to share with others who may get the same problems.
1. Solution ServerException: : GetSelfCredential: Cert missing parent
* this alone is not enough
-- rm -rf /var/lib/sfa/authorities/
-- service sfa stop
-- service sfa start
2. ServerException: Internal API error: syntax error: line 1, column 0
This is due to messed i386 vs. x86_64 installation. We are running on a CentOS5 X86_64 platform.
The function 'sign' in /usr/lib/python2.5/site-packages/sfa/trust/credential.py needs to call the following command.
which complained about not being able to load libxmlsec1-openssl.so library.
Somehow the myplc installation is using the xmlsec1-openssl.i386 dependency package instead of of xmlsec1-openssl.x86_64.
Here is what I did for fix.
-- yum erase xmlsec1-openssl.i386
*this will remove both myplc and sfa. 'yes' to that.
-- yum install xmlsec1-openssl.x86_64
-- yum install myplc
-- yum install sfa-plc sfa-client
One catch is that the libxmlsec1-openssl.so library is under /usr/lib64, which cannot be found by the code.
-- cp /usr/lib64/libxmlsec1-openssl.so /lib
I also found problem with reinstalling sfa-plc. It could not be properly erased by yum, which prevents it from being reinstalled.
Here is how to fix that.
-- yum erase sfa-plc
-- rpm -e --noscripts sfa-plc
-- yum install sfa-plc
