Any help would be most appreciated, as we currently have one group which we are no longer able to add any entries to.
openldap-bugs@openldap.org is not a general discussion list. It is for tracking bugs filed via the ITS system at <http://www.openldap.org/its>. After you file an ITS, you can then respond via email to the generated messages so that data goes into the ITS.
Given the multitude of issues fixed since 2.4.11, I would advise you upgrade to the latest stable (2.4.19) for those reasons alone. It would be good to know if you still see this issue, and I wonder if it is possibly related in some way to ITS#6327, although that is with searches on an entry with an attribute with many values.
