[Samba] Update from el7.4 to el7.5 broke samba 4.6.14

[L.P.H. van Belle]

Extract the samba tar.gz 
Enter the folder. 

Run : grep ^VERSION lib/{talloc,tdb,tevent,ldb}/wscript
Thats what you need. 

But really, dont use 4.8.0 on upgrading any samba version, wait for 4.8.1 in that case. 

Some version numbers for you. Check what your distro supports and match samba with it or rebuild a higer version for your os. 

samba-4.8.0+dfsg# grep ^VERSION lib/{talloc,tdb,tevent,ldb}/wscript
lib/talloc/wscript:VERSION = '2.1.11'
lib/tdb/wscript:VERSION = '1.3.15'
lib/tevent/wscript:VERSION = '0.9.36'
lib/ldb/wscript:VERSION = '1.3.2'

samba-4.7.7+nmu# grep ^VERSION lib/{talloc,tdb,tevent,ldb}/wscript
lib/talloc/wscript:VERSION = '2.1.9'
lib/tdb/wscript:VERSION = '1.3.14'
lib/tevent/wscript:VERSION = '0.9.34'
lib/ldb/wscript:VERSION = '1.2.3'

samba-4.6.15+nmu# grep ^VERSION lib/{talloc,tdb,tevent,ldb}/wscript
lib/talloc/wscript:VERSION = '2.1.9'
lib/tdb/wscript:VERSION = '1.3.12'
lib/tevent/wscript:VERSION = '0.9.34'
lib/ldb/wscript:VERSION = '1.1.29'

Best hint i can give here is.. 
For now use samba 4.7.7
