This is expected behaviour in Koha 18.05, see 
https://koha-community.org/koha-18-05-released/

"It is no longer possible to use the database user (defined in 
koha-conf.xml) to login into Koha. You should first create a 
superlibrarian patron and use it for logging in. See the script 
misc/devel/create_superlibrarian.pl"

Hope this helps.

Best wishes: Michael
