To improve the search performance, Directory Server has several new indexes.
Workaround: After you install Access Manager with an existing Directory Information Tree (DIT), rebuild the Directory Server indexes by running the db2index.pl script. For example:
# ./db2index.pl -D "cn=Directory Manager" -w password -n userRoot
The db2index.pl script is available in the DS-install-directory/slapd-hostname/ directory.
