Samba 4 error with compiled dlz bind

Message

Good afternoon I am with some clients running samba 4 compiled with dns using the bind however when updating the client version of samba compiled and not the distribution the bind dlz_dlopen failed to open library '/ usr / local / samba / lib / bind9 / dlz_bind9_9. So '- /usr/lib/x86_64-linux-gnu/private/libreplace-samba4.so: version `SAMBA_4.4.14' not found (required by /usr/local/samba/lib/libsamba-util.so.0) Of the problem with this it claims that this files does not find /usr/lib/x86_64-linux-gnu/private/libreplace-samba4.so compatibility with the updated version of samba the strange that this file has inside the samba folder compiled in / Usr / local / samba / lib / private /.

After updating this libreplace-samba4.so comes the problem is to replace or rename the system file so this in the samba folder ok the bind works more after you displaces and tries to login with the su command of the segmentation fault and the only one Thing to log in and if you give sudo-command thus having the user the sudo privilege. If you log in via tty it logs in via root direct but if you connect by any user and try to call su it's error segmentation.

This happens only with samba using bind9dlz it's internal dns usage does not happen this error.

strace su
