mysql  Ver 14.14 Distrib 5.1.49, for debian-linux-gnu (i486) using 
readline 6.1

and using mysql or mysqli doesn't solve the problem that the last 
login time isn't updated.

I had the same problem too, I resolved it by adding 1 dummy record in 
the imp_schema_info table, after that I clicked again on the link: DB 
Schema is out of date, and after that it said that all db Schema's are 
ready...

But I see a new problem: If I use DB storage for session handling, 
then the last login time isn't updated between sessions.
I will open a ticket for that.

Sorry, didn't you say the db error goes away when the port setting was 
removed? Is that no longer the case then? What db errors are you 
getting now?

I don't think so... I have setup socket connection to mysql :
   $conf['sql']['username'] = 'horde';
   $conf['sql']['password'] = '********';
   $conf['sql']['socket'] = '/var/run/mysqld/mysqld.sock';
   $conf['sql']['protocol'] = 'unix';
   $conf['sql']['database'] = 'horde';
   $conf['sql']['charset'] = 'utf-8';
   $conf['sql']['splitread'] = false;
   $conf['sql']['ssl'] = false;
   $conf['sql']['phptype'] = 'mysqli';

I have been able to investigate a bit more in this issue and it 
happens only if I set MySQL as the sessionhandler backend. If I let 
the PHP default (file) choice then access to the DB is working fine.
Why this was working in H3/IMP4 and no more in H5/IMP4 ?

This sounds like duplicate of Bug: 9738
Sounds like a configuration issue.

Hi again,

I made several test and now I can confirm that any update on any table 
is not working except:
horde_cache
horde_sessionshandlers
It seems that I am facing an issue with some mysql connections.
MySQL is setup to use mysqli in Horde configuration
when I turn it to "MySQL" only then I got an error stating that the 
port should not be mention in the conf.php. If I remove the line
$conf['sql']['port'] = 3306;
in my conf.php file then horde is working again but IMP complains that 
it cannot access the IMAP server...
I don't understand what happens here...
the Horde3/IMP4 used to work pretty well on this server (until I 
upgraded to php 5.3.5)...

The attachment has not been saved correctly... Here it is

Also, I have noted lot of PHP ERROR in the log file.
Is Horde compliant with php5.3.5 ?
I am also running MySQL 5.1.51

I do not see erro in MySQL especially at all !

I have attached a dump of my horde and imp conf.php files in the 
ticket. As you can see MySQL is correctly setup (and we can see access 
in the log files i have joined to my previous message).

any idea ?

weird. This works fine for me here.

Any errors in the mysql log? Are you 100% sure the database horde is 
set to use is the same that you are dumping?

Hi Michael,

Sorry for this late answer...

So yes the conf.php file is set to use SQL.
In the ZIP attachment there are 2 files
horde.sql: SQL export ==> you will see the export for my 
imp_schema_info table has been created but is empty.
horde_updateDBSchema.log: extract of the log file ==> You will see the 
following line nr 1689:
2011-03-28T14:44:48+02:00 DEBUG: HORDE [horde] SQL  (0,0001s)
        UPDATE imp_schema_info SET version = 1 [pid 20838 on line 773 of 
"/usr/share/php/Horde/Db/Adapter/Base.php"]
But the database has not been updated !

What happens ?

Thanks for your support,
Antoine.

What is the content of imp's schema table?

Have you verified that the horde config is still setup to use the sql 
prefs backend? Any errors in the log(s)?

Hi Again,

I do not know if this is linked to this bug, but since I installed 
IMP, the user preferences are no longer stored in the horde_pref table.
for instance, the "last login" entry is no more updated for existing 
users nor created for new users !
My environment:
gentoo linux
php 5.3.5
mysql 5.1.51

I have just installed Horde4/IMP5 RC1
The horde DB has been created from the Horde configuration browser window.
I have now installed IMP and configured it.
The configuration window mentions that DB Schema is out of date and so 
I have the "Update DB" button.
If I click on it, evreything is going fine (I can see the to imp 
tables in my horde DB : imp_schema_info and imp_sentmail), but the 
configuration window still complains that the DB schema is out of date.

How to solve this bug ?

Thanks for your support,
Antoine
