On Horde Webmail "User xxx is not authorised for xxx"

[~Phil~]

If you are getting the error with Horde webmail such as follows

"User xxx is not authorised for xxx"

It might be the case that the Database for horde might have gone corrupt. If so you can fix it by referring below steps which worked for me..

First take the backup of the mysql database used by horde. The database named horde is present under /var/lib/mysql.
Please use the following commnad to take backup

cd /var/lib/mysql
mysqldump horde > horde.sql

Once you have the backup drop the horde database using the following command.. as we have the backup we should not worry

mysqladmin drop horde

Now we will try to reset the horde, using the following script

/scripts/fullhordereset

This script will update hodrde and create a new database for horde

Now please try to check and repair the horde database..

mysqlcheck -r -o horde

If the report is Ok you need not worry abot any thing and you may try to login horde now.. I am sure the error would have been disapeard !
