[Fedora-directory-devel] Please Review: (208058) "decoding error" when using GSSAPI and adding new entries

Bug(s) fixed: 208058
Bug Description: When adding "large" entries or making "large" 
modifications over
    a connection using SASL mechanisms that provide encryption, the 
server returns
    a decoding error to the client.

Branch: HEAD
Fix Description:  It turns out that this is a data size related issue 
that is
    specific to using SASL mechanisms that encrypt the payload.  This 
problem will
    be triggered by a SASL payload that is larger than 512 bytes once it 
is decrypted.

    Internally, we have a buffer that holds the decrypted SASL payload.  
This data
    is copied into a 512 byte buffer inside the sasl_recv_connection() 
function.
    If the decrypted data is larger than 512 bytes, we save an offset to 
be used to
    get the remaining data on the next call to sasl_recv_connection().   The
    problem is that we ignore this offset when copying the data between 
buffers on
    the subsequent call to sasl_recv_connection().

    The fix is to start copying data out of the decrypted buffer from 
the offset.
