Having thought about this some more I now think that the problem
is to do with read/search rather than add. The last value in the
list cannot be matched however it got there.

The test data I uploaded with the ITS contains this group entry:

dn: cn=tenK,ou=groups,o=test,dc=example,dc=org
objectclass: groupOfNames
cn: tenK
member: uniqueIdentifier=a_000000,dc=example,dc=org
member: uniqueIdentifier=a_000001,dc=example,dc=org
member: uniqueIdentifier=a_004994,dc=example,dc=org
member: uniqueIdentifier=a_004995,dc=example,dc=org
member: uniqueIdentifier=a_004996,dc=example,dc=org
member: uniqueIdentifier=a_004997,dc=example,dc=org
member: uniqueIdentifier=a_004998,dc=example,dc=org
member: uniqueIdentifier=a_004999,dc=example,dc=org
member: uniqueIdentifier=a_005000,dc=example,dc=org

If I do a search for any value except the last one, it succeeds:

./bound-search member=uniqueIdentifier=a_004999,dc=example,dc=org
# tenK, groups, test, example.org
dn: cn=tenK,ou=groups,o=test,dc=example,dc=org
objectClass: groupOfNames
cn: tenK
member: uniqueIdentifier=a_000000,dc=example,dc=org
member: uniqueIdentifier=a_000001,dc=example,dc=org
member: uniqueIdentifier=a_004994,dc=example,dc=org
member: uniqueIdentifier=a_004995,dc=example,dc=org
member: uniqueIdentifier=a_004996,dc=example,dc=org
member: uniqueIdentifier=a_004997,dc=example,dc=org
member: uniqueIdentifier=a_004998,dc=example,dc=org
member: uniqueIdentifier=a_004999,dc=example,dc=org
member: uniqueIdentifier=a_005000,dc=example,dc=org

# search result
search: 2
result: 0 Success

./bound-search member=uniqueIdentifier=a_005000,dc=example,dc=org
... this does not find anything

This explains why the add and modify operations failed in such
an odd way.
