I have started slapd creating a debug file with following command: slapd -d -1 1>/tmp/slapd-debug.log 2>&1

The debug file is attached to this email.

How can I fix this issue?

You have a file in /etc/ldap/slapd.d that doesn't belong there.

57d54094 ldif_read_file: read entry file without checksum: "/etc/ldap/slapd.d/cn=config/olcDbIndex.ldif" 57d54094 => str2entry: "dn: olcDatabase={1}hdb,cn=config changetype: modify add: olcDbIndex olcDbIndex: entryUUID eq

The contents of /etc/ldap/slapd.d are slapd's private internal data. You should not touch them, nor store your own things there.

Removing /etc/ldap/slapd.d/cn=config/olcDbIndex.ldif should fix your problem.
