The package horde-kolab does not install correctly

Operating system		Distribution		Kolab version
Applies to:	probably applies to all *NIX systems	Applies to:	probably all distributions	Applies to:	Kolab 2.1_rc1 + Horde
Found on:	Linux	Found on:	OpenPKG	Found on:	Kolab 2.1_rc1 + Horde

Problem

• You don't see a login screen when you try to access http://your-domain.com/horde.
• You do not see any PHP scripts (with the ending *.php) in /kolab/var/www/kolab/horde
• There are errors in your build log that indicate a chown problem with installing horde-kolab

Solution

If installing this package fails, you should try to clean your RPM build environment. You can run

rm -rf /kolab/RPM/PKG/*
rm -rf /kolab/RPM/TMP/*
rm -rf /kolab/RPM/SRC/*

Afterwards, try to run the installation procedure again:

sh obmtool kolab 

There is no guarantee that this will help, though.

On login I'm returned and told that login failed though I used the correct password

Operating system		Distribution		Kolab version
Applies to:	probably applies to all *NIX systems	Applies to:	probably all distributions	Applies to:	Kolab 2.2_* + Horde
Found on:	Linux	Found on:	OpenPKG	Found on:	Kolab 2.2_* + Horde

Problem

There Horde log file also states that the user credentials were invalid.

Solution

Your machine probably has no real DNS entry. Make sure you enter your fully qualified host name into /etc/hosts.

Also, check your log files for errors. Does the IMAP server see your login attempt?

On login I'm returned to the login screen without an error message

Operating system		Distribution		Kolab version
Applies to:	probably applies to all *NIX systems	Applies to:	probably all distributions	Applies to:	Kolab 2.2_* + Horde
Found on:	Linux	Found on:	OpenPKG	Found on:	Kolab 2.2_* + Horde

Problem

On login, the screen turns white for a short time but you are returned to the login screen. There is no error message, but the Horde log file states that the user successfully logged into the system.

Solution

There are several possible reasons for this:

• Wrong cookie path in horde/config/conf.php
• Missing PEAR packages
• Unwritable temporary directory
• Syntax errors in edited config files

Check your log files for errors. Also check the configuration files for errors you might have introduced when editing them.

On login, apache crashes closing the connection or gives an empty php page

Operating system		Distribution		Kolab version
Applies to:	probably applies to all *NIX systems	Applies to:	Debian	Applies to:	Kolab 2.2.0
Found on:	Linux	Found on:	Debian lenny/sid amd64	Found on:	Kolab 2.2.0

Problem

Once you try to login to Horde, it doesn't matter if the login user and password are right or wrong, you always get either a "connection to host was broken" message or (depending on the web browser) a php file that is 0 bytes long.

Solution

The apache process serving the page gives a segmentation fault in a call to _nss_db_getprotobyname_r (called from getprotobyname_r, getprotobyname and tcp_socket_open respectively).

The problem is solved by removing the libnss-db package from your system.

On login ,I just get a welcome message, but no username/password fields

Operating system		Distribution		Kolab version
Applies to:	probably applies to all *NIX systems	Applies to:	probably applies to all distributions	Applies to:	Kolab 2.2.*
Found on:	Solaris	Found on:	Solaris	Found on:	Kolab 2.2.1

Problem

When connecting to Horde you see the "Welcome to Horde" block but there is no section that would allow you to enter your user credentials.

Solution

Try to remove all old session data from the temporary directory used by horde (/kolab/var/kolab/www/client/tmp or /kolab/var/kolab/tmp).

Please enter issues (and maybe solutions) you had when installing Horde into Kolab bug tracker or send a mail to the mailing list.
