[Samba] ldb: unable to dlopen

[Micha Ballmann]

Hi,

i upgraded my domain controller (dc1 and dc2, Ubuntu 18.04, compiled 
version of samba). It was a in-place upgrade from samba 4.11.7 to 4.12.3

Now I get the following error:

# samba-tool drs showrepl

ldb: unable to dlopen /usr/local/samba/lib/ldb/local_password.so : 
/usr/local/samba/lib/private/libsamdb-common-samba4.so: version 
`SAMBA_4.11.7' not found (required by 
/usr/local/samba/lib/ldb/local_password.so)
ldb: unable to dlopen /usr/local/samba/lib/ldb/simple_dn.so : 
/usr/local/samba/lib/private/libdsdb-module-samba4.so: version 
`SAMBA_4.11.7' not found (required by /usr/local/samba/lib/ldb/simple_dn.so)
ldb: unable to dlopen /usr/local/samba/lib/ldb/simple_ldap_map.so : 
/usr/local/samba/lib/private/libldbsamba-samba4.so: version 
`SAMBA_4.11.7' not found (required by 
/usr/local/samba/lib/ldb/simple_ldap_map.so)

...

But replication output shows fine.

How can i fix this?
