[Solved] 1.5 Master/Slave "stringify"???

[exekias]

It seems that ldap.conf has not been written, maybe you forgot to create ldap-slave.conf.mas file?

Yes. No.
Before accessing the web interface I did copy the content of
http://trac.ebox-platform.com/browser/trunk/client/usersandgroups/stubs/ldap-slave.conf.mas?rev=18330 into a newly created file at the same location as ldap.conf.mas exists, in: /usr/share/ebox/stubs/usersandgroups:

Code: [Select]

root@egw:/usr/share/ebox/stubs/usersandgroups# ls -al | grep ldap
-rw-r--r-- 1 root root   846 2010-08-04 18:18 ldap.conf.mas
-rw-r--r-- 1 root root   331 2010-08-09 17:46 ldap-slave.conf.mas

After realizing that ldap.conf is missing I copied ldap-slave.conf.mas manually to /etc/ldap.conf and adjusted two lines:

Code: [Select]

base dc=ps,dc=ebox,dc=lan
uri  ldap://10.2.102.1
I know that this is basically correct because I can successfully access the master by using "ldapsearch -x uid=ub" on the command line and getting the correct response.

Nevertheless I am not sure that this is the way the Master definition should look like. The web interface fails when I try to access Users and Groups with "An internal error has occurred" and in the ebox.log file I can read:

Code: [Select]

Probably I should wait for the next iteration of your packages and reinstall the slave then - I have no problem to wait :-)

Thank you

My server is not in a Master/Slave configuration - its just as single server, but I'm noting the same behavior with LDAP and some of the errors look very much like the same ones I'm getting.  Is there a procedure to complete purge perl, apache, ebox, and all depedent modules and configuration files and start from scratch (aside from the obvious reformat)?

To remove all eBox-components try:

Code: [Select]

~# apt-get --purge remove ebox*
To additionally remove now unused dependencies:

Code: [Select]

~# apt-get --purge autoremove

I have tried with this solution but i continues getting this error:

Well, the last time I ran the 'sudo apt-get autoremove' command, it blew away my gnome desktop.  So I'm not sure how well that would work... Although I did note some updates last night that I'll run.  I plan to run the ebox purge and then the autoremove command again and then start from scratch.

[UdoB]

Probably I should wait for the next iteration of your packages and reinstall the slave then

With the availability of ebox-usersandgroups_1.5.5-0ubuntu1~ppa1~lucid1_all.deb I gave it another try. Unfortunately without success.

My notes for this trip:

~#apt-get --purge remove slapd ldap-utils ebox* samba* apache* redis*

~#reboot

Best regards

[darkstar702]

My ebox problem is solved and its up and running again flawlessly.  As per some of the suggestions in the forum, I did the following:

'sudo apt-get purge ebox-all'
'sudo apt-get purge slapd'
'sudo apt-get purge apache2'
'sudo apt-get purge ubuntu-desktop'
'sudo apt-get autoremove'

Once I rebooted, I reloaded ebox using the 'sudo apt-get install ebox' command, and then reloaded my Gnome desktop on the server without any of the "suggested installation components."  This resulted in a perfectly operating server, perfectly operating ebox system, and smooth set of updates. 

I'll be trying out the SAMBA shares later this evening.  Many thanks to all for the suggestions!

This resulted in a perfectly operating server, perfectly operating ebox system, and smooth set of updates. 

Thank you for the report. I followed you sequence and had no success.

I did see some error messages in /var/log/ebox/ebox.log though.

Just for the record here is what I did:

Code: [Select]

Remove all ebox, slapd, apache2 + "autoremove"

Note: I had _no_ packages installed with "desktop" in its name.


~# apt-get --purge remove libldap-2.4-2

~# apt-get --purge remove liborbit2 # just uninstalled because it comes from ebox repository

~# rm -rf /etc/ldap # there were old artefacts from slapd

~# rm -rf /var/lib/ebox-usercorner/ # there were old artefacts

<reboot>

~# aptitude install ebox

~# aptitude install ebox-usersandgroups

First access to https://.../ebox, go immediately to Ldap and toggle Master --> Slave.

Do NOT "Save changes"

Go to Module Status. Activate "Users and Groups"
