Sumit, 

Yes exactly.  

   override_homedir = %o

would return the original  home directory retrieved from the identity provider.  What would be nice is another % flag, which retrieves the original home dir, but lower cases this original home dir.  for instance:

   override_homedir = %L

(%l is already in use.)

Or an equiv option for case_sensitive (which is for user and groups only).    Say:

    case_sensitive_homedirs = {True|False|Preserving}

Hi,

you are right, currently SSSD uses the home directory string provided by
AD as is without modifications. I guess you are looking for something
like '%o' for override_homedirs which does not add the original value
but the lower-case version.
