It sounds as if you are saying that the users have the same SID as the
domain.  However some groups have incorrect SID's.

If you are keeping the POSIX and Windows user information in LDAP, you can
do the following:

Make a backup of the folder containing the ldap data.

Use ldapsearch to export the contents of the ldap directory to a file.  This
provides a second backup

Use ldapsearch  to dump the group information to a file.

Modify the SID information in the second (group) file and use ldapmodify to
bring the correct information back into the ldap directory.

This is based on the assumption that the domain's SID is correct and the
users' SID's are correct. Only the groups' SID's are incorrect.
