simple_password_check settings on both master and slave
On master side, create an user with invalid password
CREATE USER USR_RO@'10.1.1.26' IDENTIFIED BY 'bsg9#d.cem#!85'; – No Upper Case Letter
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
The user was not created on master server, but for some reason binlog has written to disk.
On slave side, replication slave stops
Query caused different errors on master and slave. Error on master: message (format)='Your password does not satisfy the current policy requirements' error code=1819 ; Error on slave: actual message='no error', error code=0. Default database: ''. Query: 'CREATE USER USR_RO@'10.1.1.26' IDENTIFIED BY 'bsg9#d.cem#!85''
Meanwhile, I can see the new user has been created on slave server, the behaviour is strange.
