Error: "Status: 500 Internal Server Error, Description: Datastore Error" when trying to access formfill page using external secret store

Formfill policy defined that reads and writes secrets to a remote eDirectory LDAP user store.
The LDAP replica has the option 'Install NMAS SAML method' enabled
The remote eDir has the SAML methods installed

When a user tries to fill the HTML form using the FormFill policy enabled on the protected resource, the following error is reported on the browser:

Status: 500 Internal Server Error, Description: Datastore Error

Even with auto submit disabled, we get this error - the attributes that we try and fill with secret store cannot be read or written. Looking at the DSTRACE output on the LDAP user store (with +NMAS, LDAP and TIME flags enabled), the following error is reported

Install  the 'compat-2009.1.19-2.2.i586.rpm' on the SLES 11.0 server running eDir 885-32/64 bit or greater. The SAML NMAS method has a dependency on the module  libstdc++-libc6.2-2.so.3 and if it's not present, it won't load and will cause all the problem. This is required for the SAML NMAS method used by eDir and it's supporting libraries to initialise correctly. Once done, the IDP Cluster can use eDir for Secret Store without problems.

For SLES 11 x86-32 and x86-64 builds, this compat module is still required. The compat rpms are located in the SLES11-Extras repository, which is not enabled by default.

Once the SLES11-Extras is enabled, search for and install the appropriate compat rpm per architecture below.

SLES 11 32bit - compat (compat-2009.1.19-2.1)
SLES 11 64bit - compat-32bit  (compat-32bit-2009.1.19-2.1)
