Configure Ezeelogin to authenticate using Windows_AD(Pam-LDAP) in Ubuntu 16.x 18.x 20.x?

Integration of WINDOWS-AD (PAM-LDAP) in Ubuntu

Make sure that PHP-LDAP extension is installed on the server

[email protected]:~# apt-get install php5-ldap/php7-ldap /php-ldap

1. Login to Web-GUI > open settings > LDAP

Add the details of LDAP configurations & Check the Windows Active Directory

2. open Settings > General > Authentication > change webpanel authentication to LDAP & Check External SSH Auth

3. Select the LDAP users and import them to ezeelogin

You can confirm the imported LDAP users were listed in the Users

Now you can log in to ezeelogin with LDAP user in ezeelogin GUI

After importing the users to Ezeelogin, log in with the user and set up security code for the user under Account > Password > New Security Code.

4. Make sure that UNIX ATTRIBUTES is enabled on WINDOWS(2003,2008,2012) SERVER

You do not need to install unix attributes on windows 10 and windows 2016 server OS

Enter the below command

Dism.exe/online/enable-feature /featurename:nis /all

Reboot the server to complete the installation

5. Make sure to add the values for UID, GID, Login Shell, Home Directory

Win 2008 Unix Attributes

For Window 2016 AD user set the attributes such as uidNumber = 10001 , gidNumber = 12001 , unixHomeDirectory = /home/jake , loginShell=/usr/local/bin/ezsh

NOTE: For the Unix Attributes uidNumber, gidNumber, login shell to be visible, make sure to click on the Filter button and select ONLY " Show Only Writable Attributes" as shown below.

Let's configure PAM_LDAP Authentication for SSH

1. Install pam-LDAP module by the following command

[email protected]:~# apt-get install ldap-auth-client ldap-auth-config nscd

2. Enter LDAP URI, Base dn & select LDAP version 3

Enter the details when it is prompted or you can add it later as follows.

3. Add Binddn,bind password & Active Directory Mappings to /etc/ldap.conf

[email protected]:~# nano /etc/ldap.conf
 
 base OU=developers,DC=adez,DC=com
 uri ldap://192.168.1.15
 binddn cn=admin,dc=eztest,dc=net
 bindpw [email protected]#234JH56hj^7

And add binddn and bind password to the file

In Ubuntu 16.x, run the command " ln -s /etc/ldap /etc/openldap" as well.

4. Search for RF 2307 (AD) mapping & add or uncomment the following lines

nss_map_objectclass posixAccount user
nss_map_objectclass shadowAccount user
nss_map_attribute uid sAMAccountName
nss_map_attribute homeDirectory unixHomeDirectory
nss_map_attribute shadowLastChange pwdLastSet
nss_map_objectclass posixGroup group
nss_map_attribute uniqueMember member
pam_login_attribute sAMAccountName
pam_filter objectclass=User
pam_password ad
nss_override_attribute_value loginShell /usr/local/bin/ezsh

5. Append 'ldap' to password,group & shadow in /etc/nsswitch.conf

[email protected]:~# cat /etc/nsswitch.conf

# /etc/nsswitch.conf

# Example configuration of GNU Name Service Switch functionality.

# If you have the `glibc-doc-reference' and `info' packages installed, try:

# `info libc "Name Service Switch"' for information about this file.

passwd: compat ldap

group: compat ldap

shadow: compat ldap

hosts: files mdns4_minimal [NOTFOUND=return] dns

networks: files

protocols: db files

services: db files

ethers: db files

rpc: db files

netgroup: nis

6. Enable autocreate home directory on login by adding the following to /etc/pam.d/common-session by the following command

[email protected]:~# echo "session optional pam_mkhomedir.so skel=/etc/skel umask=077" >> /etc/pam.d/common-session

7. Edit /etc/pam.d/common-password and add the entries for ldap.

[email protected]jumpserver:~# vi /etc/pam.d/common-password

#look for the lines starting with password and add the line below to enable authentication via ldap.

password [success=1 user_unknown=ignore default=die] pam_ldap.so use_authtok try_first_pass

8. Restart nscd service

[email protected]:~# service nscd restart  

Ensure the login shell of ldap user is /usr/local/bin/ezsh

Now run the id/finger command and see whether you are able to get AD user details

[[email protected] ~]# finger jake
Login: jake           Name: jake t
Directory: /home/jake     Shell: /usr/local/bin/ezsh
Last login Wed Jun 13 05:02 (EDT) on pts/1 from 10.1.1.13
No mail.
No Plan.
[[email protected] ~]# id jake
uid=10001(jake) gid=120001(domain users) groups=1547600513(domain users)

Run an ldapsearch to check the values returned from your AD server as follows. This is used for troubleshooting. Ensure that it returns the values of uid,gid,home directory, and login shell.

[[email protected]]# ldapsearch -x -LLL -E pr=200/noprompt -h 10.11.1.164 -D "[email protected]" -w admod_2016 -b "cn=jake,cn=users,dc=ad2016,dc=admod,dc=net"
