Zimbra Integration in FreeIPA

At this point, I'm assuming you have a functional zimbra-server up and running including dns-records.

In my case, I was using my 2 FreeIPA-Servers to handle DNS and authentication. You can add a MX-Record to integrated DNS by running

 [archy@ipa01 ~]$ ipa dnsrecord-add archyslife.lan zimbra --mx-preference=0 --mx-exchanger=zimbra.archyslife.lan

 [archy@ipa01 ~]$ ipa dnsrecord-add archyslife.lan zimbra --mx-rec="0 zimbra.archyslife.lan"

Note: the hostname of the machine I'm using is zimbra and the dns-zone is archyslife.lan. The 'mx-rec' option is used for raw mx-records meaning the preference and exchanger must be given.

First we will have to ensure, that we will still be able to access the administration panel even though there is no connection to the LDAP server. You can do this by issuing the following command:

 [archy@zimbra ~]$ sudo su -l zimbra  
 [zimbra@zimbra ~]$ zmprov modifydomain archyslife.lan zimbraAuthFallbackToLocal TRUE

We will also have to create a account for zimbra to bind to for the IPA-Service. I'll be using this LDIF to create the service-account. Contents of the LDIF:

 dn: uid=zimbra,cn=sysaccounts,cn=etc,dc=archyslife,dc=lan  
 changetype: add  
 objectclass: account  
 objectclass: simplesecurityobject  
 uid: zimbra  
 userPassword: i_am_a_secret_password  
 passwordExpirationTime: 20380119031407Z  
 nsIdleTimeout: 0

Next, we have to import it to the Directory Server

 [archy@ipa01 ~]$ sudo ldapmodify -h ipa01.archyslife.lan -p 389 -x -D "cn=Directory Manager" -w directory_manager_password -f zimbra_sysacc.ldif

That's it. The IPA Directory is set up.

Now we'll open up the administrative console from zimbra by pointing our browser to https://zimbra.archyslife.lan:7071/zimbraAdmin.
The Login Credentials for this are your the admin account you created during the setup.

Welcome Screen for the admin console

In the left panel, click on 'Configure' --> 'Domains' -->
select your domain and click on 'Authentication' -->
Click on the little gearwheel on the upper right hand corner and choose 'configure authentication'. Use external LDAP

Enter your LDAP-Server-Names, in my case it's:

 ipa01.archyslife.lan  
 ipa02.archyslife.lan

Use the following filter for LDAP:

 (&(objectClass=inetOrgPerson)(objectClass=posixAccount)(uid=%u))

And the following LDAP search base:

 cn=users,cn=accounts,dc=archyslife,dc=lan

It should look something like this.

Click next tick the box for using DN / Password to bind to external server.
The DN required here is the dn used in the ldif file we created and imported earlier.

 uid=zimbra,cn=sysaccounts,cn=archyslife,dc=lan  
 Bind password: i_am_a_secret_password  
 Confirm password: i_am_a_secret_password

the domain binding

Now go ahead an test with one of your created users. The test should be successfull.

Your Zimbra-Server is now registered to FreeIPA and can obtain user data from the Directory Server.

Dynamic DNS with BIND and ISC-DHCP

I personally prefer to work with hostnames instead of ip-addresses. If you have anything like freeipa or active directory, it will do that for you by registering the client you added to your realm to the managed dns and edit the records dynamically. We can achieve the same goal with just bind and isc-dhcp. I'll use a raspberry pi with raspbian 9 for this setup. So here is a quick tutorial on how to configure the isc-dhcp-server to dynamically update bind. First set a static ip to your server. [archy@ddns ~]$ sudo vim /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto eth0 iface eth0 inet static address 172.31.30.5 network 172.31.30.0 broadcast 172.31.30.255 netmask 255.255.255.0

LACP-Teaming on CentOS 7 / RHEL 7

What is teaming? Teaming or LACP (802.3ad) is a technique used to bond together multiple interfaces to achieve higher combined bandwith. NOTE: every clients speed can only be as high as the single link speed of one of the members. That means, if the interfaces I use in the bond have 1 Gigabit, every client will only have a maximum speed of 1 Gigabit. The advantage of teaming is, that it can handle multiple connections with 1 Gigabit. How many connections depends on the amount of your network cards. I'm using 2 network cards for this team on my server. That means I can handle 2 Gigabit connections at full rate on my server provided the rest of the hardware can deliver that speed. There also exists 'Bonding' in the Linux world. They both do the same in theory but for a detailed comparison check out this article about teaming in RHEL7 . To create a teaming-interface, we will first have to remove all the interface configurations we've done on the (soon to be) sla

Push logs and data into elasticsearch - Part 2 Mikrotik Logs

This is only about the setup of different logging, one being done with Filebeat and the other being done with sending logging to a dedicated port opened in Logstash using the TCP / UDP Inputs. Prerequesites: You'll need a working Elasticsearch Cluster with Logstash and Kibana. Start by getting the Log Data you want to structure parsed correctly. Mikrotik Logs are a bit difficult since they show you Data in the interface which is already enriched with Time / Date. That means a message that the remote logging will send to Logstash will look like this: firewall,info forward: in:lan out:wan, src-mac aa:bb:cc:dd:ee:ff, proto UDP, 172.31.100.154:57061->109.164.113.231:443, len 76 You can check them in the grok debugger and create your own filters and mapping. The following is my example which might not fit your needs. Here are some custom patterns I wrote for my pattern matching: MIKROTIK_DATE \b(?:jan(?:uary)?|feb(?:ruary)?|mar(?:ch)?|apr(?:il)?|may|jun(?:e)?|jul(?

FreeIPA - Integrating your DHCPD dynamic Updates into IPA

I recently went over my network configuration and noticed that the dhcp-leases were not pushed into the IPA-DNS yet. So I thought, why not do it now. The setup is very similar to setting it up on a single bind instance not managed by IPA (I've already written a guide about this here ). recently went over my network configuration and I noticed that I've never put my My setup is done with the following hosts: ipa01.archyslife.lan - 172.31.0.1 inf01.archyslife.lan - 172.31.0.5 First of all, create a rndc-key: [archy@ipa01 ~]$ sudo rndc-confgen -a -b 512 This will create the following file '/etc/rndc-key' [archy@ipa01 ~]$ sudo cat /etc/rndc.key key "rndc-key" { algorithm hmac-md5; secret "secret_key_here=="; }; We also need to make named aware of the rndc-key and allow our remote dhcp server to write dns entries: [archy@ipa01 ~]$ sudo vim /etc/named.conf ... include "/etc/rndc-key&quo

SSSD - Debugging PAM permission denied

Sometimes there's weird errors in IT that occur on random chance. I've had such an encounter with SSSD in combination with IPA(+AD-Trust) recently, where only sometimes, a connection to one of the IPA-Servers would fail with this error: Jul 13 13:36:42 ipa02.archyslife.lan sshd[3478]: pam_sss(sshd:account): Access denied for user runner: 4 (System error) Jul 13 13:36:42 ipa02.archyslife.lan sshd[3478]: fatal: Access denied for user runner by PAM account configuration [preauth] In my case, it was only happening sometimes when running a basic system setup role using ansible on every host in the entire environment. This way, there was no consistent pattern besides being the same host every time if it failed. First up, add the 'debug_level=X' to every section required in the /etc/sssd/sssd.conf where X is a number from 1 to 10 with 10 being the most verbose. Afterward, restart sssd and check the logs for any obvious problems. 1) If you are using local users, check the
