Title: Can't call method "attributes" on an undefined value at Ldap.pm line 226
Post by: binary-two on January 17, 2010, 02:58:31 am

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.

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!

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

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

Title: Re: Can't call method "attributes" on an undefined value at Ldap.pm line 226
Post by: binary-two on January 18, 2010, 10:14:05 am

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

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

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

Title: Re: Can't call method "attributes" on an undefined value at Ldap.pm line 226
Post by: zergius on January 18, 2010, 03:00:33 pm

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]

Here's my output. I still have problems with slapd, ebox-userandgroups, ebox-mail.

Ok. Do the following:
sudo rm /var/lib/dpkg/info/slapd.postinst
then edit:
/etc/ldap/slapd.d/cn\=config/olcDatabase={0}config.ldif with vim or whatever, and you can see two lines that start with olcAccess:

Code: [Select]

olcAccess: to * by dn.exact=cn=localroot,cn=config manage by * break
olcAccess: {0}to * by dn="cn=ebox,dc=vibrobloc,dc=locale" write

They are separated, move them together and change them to look like this:

Code: [Select]

olcAccess: {0}to * by dn.exact=cn=localroot,cn=config manage by * break
olcAccess: {1}to * by dn="cn=ebox,dc=vibrobloc,dc=locale" write

Then run:

Code: [Select]

sudo dpkg --configure -a

Then run again the commands I gave in the other post to see if things have been fixed. Also check the web interface to see if things are working and paste here any error you get.

Cheers

Ok, can you please run this command:
sudo cat /etc/ldap/slapd.d/cn\=config/olcDatabase\=\{-1\}frontend.ldif
and paste the output here?

If the output is something like:

Code: [Select]

dn: olcDatabase={-1}frontend
objectClass: olcDatabaseConfig
objectClass: olcFrontendConfig
olcDatabase: {-1}frontend
olcAccess: {0}to * by dn.exact=cn=localroot,cn=config manage by * break

modifiersName: cn=config
modifyTimestamp: 20100118003004Z
containing one single olcAccess line, you need to add two more lines, so it looks like:

Code: [Select]

...
olcAccess: {0}to * by dn.exact=cn=localroot,cn=config manage by * break
olcAccess: {1}to dn.base="" by * read
olcAccess: {2}to dn.base="cn=subschema" by * read
...
then run:

Code: [Select]

sudo /etc/init.d/slapd restart
sudo /etc/init.d/ebox users restart
sudo /etc/init.d/ebox mail restart

Post here the output of the commands. Cheers!

olcAccess: to dn.base="" by * read
olcAccess: to dn.base="cn=subschema" by * read

Uhm, apparently you are lacking the LDAP schema required for a master eBox.

If the rest of your setup is ok you can load it using:

Code: [Select]

sudo ldapadd -H 'ldapi://' -Y EXTERNAL -c

The command will wait for input, type this:

Code: [Select]

include: file:///usr/share/ebox-usersandgroups/master.ldif
include: file:///usr/share/ebox-usersandgroups/slaves.ldif

This should fix that problem, but if that's missing, you might miss other stuff too. Let me know :)
