Yes, plugin library is actually being loaded. But after that it pulls
libslapi.so, unsuccessfully. My bad, last time I haven't noticed an
important line in ld-linux.so debug output:

/usr/local/lib/libslapi-2-devel.so.0: error: symbol lookup error:
undefined symbol: entry2str_mutex (fatal)

That's why ltdl cannot load a plugin. However, this doesn't make things
much clearer: that entry2str_mutex symbol is definitely present in the
slapd binary, according to nm output:

[root@localhost slapd]$ nm slapd | grep entry2str_mutex
082676b0 B entry2str_mutex
