Hello folks... I update the openldap from version 2.2.28-r7 to 2.3.35-r1 using emerge. After update the slapd deamon didn't start. I enabled the log and realized that the problem was the incompatible version of the database. I then downgrade to the 2.2.28 version and when I started slapd I got the message: "/usr/lib64/openldap/slapd: error while loading shared libraries: liblber-2.3.so.0: cannot open shared object file: No such file or directory". I then reinstall and this problem doesn't happen anymore, but slapd still doesn't start and print the following messages in the log file: Jul 27 17:55:11 embedded slapd[2957]: bdb_db_init: Initializing BDB database Jul 27 17:55:11 embedded slapd[2958]: bdb(o=Embedded,c=BR): Program version 4.5 doesn't match environment version 0.22 Jul 27 17:55:11 embedded slapd[2958]: bdb_db_open: dbenv_open failed: DB_VERSION_MISMATCH: Database environment version mismatch (-30972) Jul 27 17:55:11 embedded slapd[2958]: backend_startup: bi_db_open failed!
