Other modules / I did the 6.1 upgrade now anything added to DNS won't resolve

« on: November 19, 2019, 11:20:52 pm »

I decided to do the 6.1 upgrade when the button appeared and the upgrade seemed to work fine. Everything appeared to have come up as it should.

However, I've discovered that if I add something to DNS in the same way I've done for loads of other devices I can't resolve it. To be clear, anything that was already on my server still works

Code: [Select]

dig +short odroid1.23wwc.io @192.168.6.1                           22:09:52
192.168.1.91
But anything added since the upgrade doesn't work

Code: [Select]

dig pdu1.23wwc.io @192.168.6.1                                     22:11:09

I can't see anything relevant in any log files so I went and did a bit of digging and found this (PDU1 is 192.168.1.31)

So these records haven't been created even though they're visible in the Admin UI


Anyone know what's going on?

Directory and Authentication / Struggling with LDAP authentication

« on: July 03, 2019, 08:53:54 am »

Hi all,

I've spent way too much time trying to understand what I'm doing wrong. I have searched these forums and Google in general, tried all the suggestions and still can't figure out which bit is incorrect. I'm using an up-to-date "Zentyal Development Server 6.0"

Just to clarify it's not anything "obvious", I can:

○ → ssh steve@zentyal.23wwc.io
steve@zentyal.23wwc.io's password:
Welcome to Ubuntu 18.04.2 LTS (GNU/Linux 4.15.0-54-generic x86_64)


And I can even

○ → kinit steve@23WWC.IO
steve@23WWC.IO's password:

○ → klist
Credentials cache: API:2A75BED1-1C30-4585-991E-6681BEC9CB99
        Principal: steve@23WWC.IO

  Issued                Expires               Principal
Jul  3 07:30:46 2019  Jul  3 17:30:43 2019  krbtgt/23WWC.IO@23WWC.IO

But no matter what I try, doing anything with LDAP fails

○ → ldapsearch -h zentyal.23wwc.io  -b dc=23wwc,dc=io -D CN=steve,CN=Users,DC=23wwc,DC=io -W
Enter LDAP Password:
ldap_bind: Invalid credentials (49)
   additional info: 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1

And the Zentyal Samba logs show

Auth: [LDAP,simple bind/TLS] user [(null)]\[CN=steve,CN=Users,DC=23wwc,DC=io] at [Wed, 03 Jul 2019 07:35:10.123764 BST] with [Plaintext] status [NT_STATUS_NO_SUCH_USER] workstation [(null)] remote host [ipv4:192.168.3.50:63405] mapped to [(null)]\[(null)]. local host [ipv4:192.168.2.1:389]



My main path of testing has been that the DN CN=steve,CN=Users,DC=23wwc,DC=io is wrong so I've tried 23WWC/Steve and uid= and samAccountName= and other variations but I get the same result. I did notice in my searching that in screenshots for 5.0 the LDAP page used to display the bind user and bind password. In 6.0 it only shows the base DN. This also made me wonder if there's another step I have to do to "activate" LDAP

Can anyone point out what I'm missing or doing wrong?

Thanks

Installation and Upgrades / Repeatable networking problem after apt update on 6.0

« on: May 30, 2019, 11:51:43 am »

Hi,

I've been having problems with installing Zentyal 6.0 and then performing an apt upgrade. I have tried this on an i5 machine and a couple of VMs and get the same result every time.

1) Install Zentyal
2) Go through the initial setup
3) Run

Code: [Select]

sudo apt update4) Run

Code: [Select]

sudo apt upgrade
Result:

Network configuration disappears and a /etc/netplan/01-netcfg.yaml appears but netplan isn't installed

I've searched the forums and found https://forum.zentyal.org/index.php/topic,32523.msg109278.html#msg109278 that might be the same problem but it's partly in Russian and the given fix - apt purge ubuntu-minimal - doesn't work.

Because I've lost the network connection I can't easily copy and paste logs to this post. apt/history.log does say it's installed netplan.io

Anyone know why this keeps happening? Not upgrading packages seems to be the only fix.
