Cannot Index uniqueMember ( uniqueMemberMatch)

["Wachdorf, Daniel R" <drwachd@sandia.gov>]

I am trying to setup indexing for the attribute uniqueMember.  I have added
the following line to my slapd.conf

index uniqueMember eq

When I start slapd in debug mode it get:

/usr/local/etc/openldap/slapd.conf: line 69: equality index of attribute
"uniqueMember" disallowed

I have tried 2.2.7, 2.2.8, 2.1.19.  All three versions seem to have the same
problem. 

Any ideas?

Thanks.
