Currently, when following the installation instructions, the scripts
adding clients to the database don’t work as the user `ykval_verifier`
does not have any insert rights for the table `clients`.
```
LOG_DEBUG:ykval-gen-clients:db:DB query is:SELECT id FROM clients ORDER BY id DESC LIMIT 1
LOG_DEBUG:ykval-gen-clients:db:DB query is: INSERT INTO clients (id,active,created,secret,email,notes,otp) VALUES ('1', '1', '1404359826','XXXXXXXXXXXXXXXXXXXXXXXX =','','','')
LOG_INFO:ykval-gen-clients:db:Database query error: Array ( [0] => 42000 [1] => 1142 [2] => INSERT command denied to user 'ykval_verifier'@'localhost' for table 'clients' )
LOG_ERR:ykval-gen-clients:Failed to insert new client with query INSERT INTO clients (id,active,created,secret,email,notes,otp) VALUES ('1', '1', '1404359826’,’XXXXXXXXXXXXXXXXXXXXXXXX=','','','')
Failed to insert new client with query INSERT INTO clients (id,active,created,secret,email,notes,otp) VALUES ('1', '1', '1404359826','XXXXXXXXXXXXXXXXXXXXXXXX =','','','')`
```
Therefore, update the documentation, to also grant the user
`ykval_verifier` the rights to insert and update records into the table
`clients`. No delete rights are granted, because there is an `active`
column, which should probably used over deletion of clients.
Note, the original idea was probably to use two database users. One for
inserting and updating data, and one for querying/validating it. As,
nothing is written about this though, use the existing/recommended user
for both things.
Fixes: #20 (ykval_verifier SQL user doesn't have permission to INSERT
INTO clients, breaks ykval-gen-clients)
Ubuntu 12.04 LTS will be supported until April 2017, but Ubuntu 14.04
LTS has been around long enough, so it’s well tested and probably more
common to install than 12.04 LTS. It’s supported until April 2019 [1].
