Can't call method "attributes" on an undefined value at Ldap.pm line 226

[binary-two]

Hi all,

running the latest update of 1.3 (with slapd_2.4.18) I get following error messages with all ldap-related modules:

Can't call method "attributes" on an undefined value at /usr/share/perl5/EBox/Ldap.pm line 226

Same happens in the web admin interface:

A really nasty bug has occurred
Exception
Can't call method "attributes" on an undefined value
Trace
Can't call method "attributes" on an undefined value at /usr/share/perl5/EBox/Ldap.pm line 226.

Thanks in advance!

Kind regards,

Björn

I am not 100% sure and not an expert on ldap issues, but can it be that slapd_2.4.18 breaks the system? Do others experience the same problem?

Thanks,

Björn

Do you have a configuration backup done before the update? Maybe you can try to restore it.

Anyway, the migration process is not finished yet, so these kind of things can happen. Remember that 1.3 is still beta.

Thank you for help us testing it.

[binary-two]

Thanks! It is on a testing system, so its no problem. Backups are ready to test again after the new version is ready and on the ppa.

So long,

Björn

I meant that you can try to restore the backup in your current broken installation and give us feedback about if it fixes the problem.

Hi zergius! I am going to perform and upgrade from some 1.3.X to 1.3.15 and I'll tell you how to fix your installation.

A new usersandgroups supporting upgrades from 1.3.X to 1.3.15 will be out soon.

Cheers!

[zergius]

isaak, what is you way to fix it?

J. A. Calvo, yes, when i restore backup of yesterday most of functions are restored... Only in logs module i have get this:
Exception
(in cleanup) Can't call method "disconnect" on an undefined value
Trace

Same problem here. No backup available. Big mistake.
Is there a way to fix?

[binary-two]

I quickly tried, but it was not successful (for me). What I've forgotten yesterday was to try to downgrade manually , i.e.

apt-get install slapd=version

You can get the available versions with

apt-cache policy slapd

I don't know the exact versions out of my mind right now.  And you have to fix the other dependencies (ebox-usersandgroups, etc.) as well. Could be messy to resolve everything after all.

I am sure the ebox-team will help with a fix soon. Thanks in advance for the great work!

So long,

Björn

Waiting for a fix how can i downgrade manually?

[isaac]

Hi, in the end the fix is not that easy, and we are focusing on the 1.2 to 1.4 migration at the moment.

Can you run "dpkg -l | grep slapd" and paste here the result?

Also the output of:

Code: [Select]

sudo /usr/sbin/slapd -d 256 -h "ldap:/// ldapi:///" -g openldap -u openldap -F /etc/ldap/slapd.d/
and

Code: [Select]

sudo cat /etc/ldap/slapd.d/cn\=config/olcDatabase={0}config.ldif

Cheers!

Here is my output:

@zergius: That looks quite good That is after restoring a backup in the new version, right? Are you still having problems with LDAP?

[zergius]

Sorry, guess i make one more mistake... No, I havn't any problems with LDAP, i have them with LOG module - I can't see any logs in web... When i try to see any logs i get this:

Code: [Select]

Exception
(in cleanup) Can't call method "disconnect" on an undefined value
Trace
(in cleanup) Can't call method "disconnect" on an undefined value at /usr/share/perl5/EBox/PgDBEngine.pm line 112.
About backup - I haven't use eBox eBackup, it's just tar archive of "/" exclude some directory... So I have an old versions of eBox modules...
