In
To take care of the update/upgrade, opena terminal window
and, issue the following commands:
Code Block sudo apt-get update
sudo apt-get upgrade
In a terminal window, then issue the following command.
Once that finishes, you're ready to install OpenLDAP. For this, go back to the terminal window and issue the command:Code Block sudo apt install slapd
sudo apt install slapdldap-utils
- After the installation completes, you may want to modify the
Modify the default Directory Information Tree (DIT) suffix
. Let's go ahead and do that. We'll change our DIT to dc=smab,dc=org. You can change yours to fit your company network needs. To do this, run the command:
sudo dpkg-reconfigureby changing the DIT to fit your company's network needs. For example,
dc=<org name>, dc=org
. To do so, issue the following command.Code Block sudo dpkg-reconfigure slapd
- Enter the administrator's password.
- Now we're going to add
Add initial data to the LDAP database
. We'll do thisfrom a file and create a single entry.
From yourIn a terminal window, issue the following command
:.
Code Block vi ldap_data.ldif
The following information is returned.
Code Block dn: ou=People,dc=

Note In this .ldif file, we created
...
two organizationalUnit values, People and Groups.
...
Add the entities for these OU values. One entity
...
must be nciadevtest for
...
NBIA. The uid and cn must be this name.
...
NBIA
...
uses cn to
...
as the default authentication
...
. Some software applications use uid to
...
authenticate.
Add the following entities to the LDAP server
...
.
Code Block ldapadd -x -D cn=admin,dc=smab,dc=org -W -f ldap_data.ldif
...
Use this command to search the
...
existing records. You can use the network loop IP address to test or use the real IP address.
Code Block ldapsearch -x -LLL -h 127.0.0.1 -p 389 -D cn=admin,dc=
...
<org name>,dc=org -w
...
<password>-b dc=
...
<org name>,dc=org 'uid=nciadevtest' cn givenName gidNumber
...
Result:
...
dn: uid=nciadevtest,ou=People,dc=
...
<org name>,dc=org
...
givenName:
...
First Name cn: nciadevtest
...
gidNumber: 5000

...
uid: nciadevtest

Add the records.

The LDAP server configuration

looks similar to the following.

After installing the LDAP server, use an LDAP |
...
client such as Softerra LDAP administrator to make sure the LDAP server can be accessed. Sometimes the Linux firewall will block the LDAP server by default. If the LDAP can be accessed, it is easy for NBIA to access it. |
Configuring the LDAP Administrator Client
You can add, modify, or remove records to or from the LDAP server in several ways.
- On a Linux server, use phpldapadmin to maintain the LDAP server. Refer to the following links to install phpldapadmin. (Note that phpldapadmin is not updated. There are some errors with php7.0 +).
...
- Use a Windows LDAP client such as Softerra LDAP Administrator to access the remote LDAP server.
To
We are using Softerra ldap administrator, which is a very user friendly software to maintain remote LDAP server.How to use Softerra LDAP Administrator1.
- Create a new profile.
...
- Add the server host (IP or domain), Base DN, and port.
...
- Add the bind admin information.
You can use the LDAP client to create/, delete/, and modify the entities with this information. Otherwise, you only have the read permission.
Troubleshooting
...
Note
1. The OpenLdap can be installed on an Ubuntu Server. The phpldapadmin can also can work. The Use ldapsearch also can to search the user information.
But when I tried to use You may find that when you try to use the LDAP client to access this LDAP server. The connection is timeout. There is no any response from , the connection times out with no response from the LDAP server even if I enabled all ports .
I think the reason is the Ubuntu Server is blocked the LDAP be default (Maybe firewall reason). Currently, I haven’t find the way to solve this issue yet.
2. When I installed are enabled. The user did not find any solution for this issue.
When installing OpenLDAP on Ubuntu (Desktop version). All LDAP function works by default. There is no , all LDAP functions worked without any issues. I can use any Any LDAP client tool to can access the remote LDAP server, which is on Ubuntu Desktop.
NBIA LDAP
...
Settings
...
In nbia.properties (Tomcat7.0/lib/nbia.properties), ldap.user and ldap.pass must be the administrator information of LDAP server. Modify nbia.properties as follows.
Code Block authentication.type=ldap-auth
...
ldap.url=ldap://
...
<ip address><port number> ldap.basedn=dc=
...
<org name>,dc=org
...
ldap.user=CN=admin,dc=
...
<org name>,dc=org
...
ldap.pass=
...
<password> ldap.memberOf.attribute.name=isMemberOf
...
ldap.mail.attribute.name=mail
...
ldap.group.ignore.list=PwmAdmins,devTeam,nlst,testGroup
...
public.collection.access.group.name=General User
...
product.variation=NBIA
...
Modify jaas.conf (Tomcat7.0/conf/jaas.conf) as follows:
Code Block NCIA
...
{
...
gov.nih.nci.security.authentication.loginmodules.LDAPLoginModule Required
...
ldapHost="ldap://
...
<ip address><port number>" ldapSearchableBase="dc=
...
<org name>,dc=org"
...
ldapUserIdLabel="cn"
...
ldapAdminUserName="CN=admin,dc=
...
<org name>,dc=org"
...
ldapAdminPassword=
...
<password>;
...
};
...
The jaas.conf is generated during
...
NBIA installation. The default ldapUserIdLabel is
...
cn, which means the LDAP server will search
...
the cn value, then compare it to the login username. If the user name
...
exists in the LDAP server, the LDAP server will
...
authenticate this user.
Some LDAP
...
servers may use
...
another field to store the login username
...
, such as uid. In this case, change the username value to uid. For example,
ldapUserIdLabel="cn"
...
- Restart Tomcat for the change to take effect.
