This article refers to Barracuda Message Archiver firmware version 5.1 or higher. The Barracuda Message Archiver authenticates individual users and user group membership based on authentication services you define on the USERS >Directory Services page. LDAP Configuration Video Sample LDAP server configuration: Configure LDAP To configure the Barracuda Message Archiver to use your LDAP server for authentication, enter the following details: • Server Alias – A short name or alias to the LDAP server; used only on the Barracuda Message Archiver to identify this LDAP Server. • Server Name/IP – The IP address or hostname of your LDAP or Active Directory server. • LDAP Port – The port used by your LDAP or Active Directory server. Anime Magi Season 1 Episode 8 Sub Indonesia. The default is port 389. • LDAP Encryption – The type of encryption used by your LDAP or Active Directory server.

Apr 24, 2012 Configuring OpenLDAP pass-through authentication to Active Directory. An IMAP server, another LDAP server, or anything supported by the PAM mechanism. AD and LDAP integration. External identity stores (such as Windows Active Directory) are common deployments today in enterprise environments for user management.

• Bind DN (Username) – The distinguished name (DN) of a user in your LDAP directory that has read access to all the users in LDAP. • Bind Password – The password for the user you specified in the Bind DN field.

• LDAP Search Base – The base distinguished name (DN) for the directory. For example, if your domain is test.com, your base DN might be dc=test,dc=com. • UID Attribute – The attribute that contains the user's ID. For Active Directory, it is recommended that you use sAMAccountName. For OpenLDAP, it is recommended that you use uid. • Shared Mailboxes – Specify whether to search for shared mailbox access in your Active Directory server.

When enabled, once a user performs a search on the BASIC >Users page, the User Select drop-down menu displays all mail for that user regardless of whether a domain and Saved Search filter has been applied to that user. Information from Folder Sync (Exchange Integration) tasks are used to determine shared mailboxes users have access to.

For shared mailbox information to stay up-to-date, configure a nightly. Advanced LDAP Options You can optionally add advanced LDAP filters. Entered values must match any users you want to archive mail for: • Additional Filter – Used for searching the LDAP server for additional matching entries. Enter the filter the format described by RFC 2254.

For example, to match users only: Active Directory: objectClass=user Novell eDirectory: objectClass=inetOrgPerson Open LDAP: objectClass=posixAccount • Member Groups Attribute – The LDAP attribute used to identify the groups to which an entry belongs. For example: Active Directory (recommended): memberOf Novell eDirectory (recommended): groupMembership • Group Members Attribute – The LDAP attribute used to identify the members of a group. The Group Members attribute is used to ensure that users can find mail sent to groups to which they belong.

For example: Active Directory: member Novell eDirectory: member.

#rpm -qa grep httpd #yum install httpd #yum install openssl Step2: Create DNS CNAME entry for this virtual host as adssl.linuxnix.com which should point to our server name server.linuxnix.com Step3: Create a home directory for our virtual host and index.html file #mkdir /websites/ssl #vi /websites/ssl/index.html Write something to this file then save and exit. Subtask2: Step4: Create ssl self-signed certificate for our site. What is self-signed certificate? Ans: An self-signed certificate, created locally at the server where the web site with SSL services support are to be implemented, are locally generated certificates when web site or server owner either don’t plan on having certificate signed by a CA, or the certificate is for testing of new SSL implementation.

This temporary certificate will generate an error in the client browser to the effect that the signing certificate authority is unknown and not trusted because it’s not signed by any known trusted CA authority. To generate a self-signed certificate we have to generate two things. A private key which will be with server. CSR (Certificate Signing Request) which is used to generate self-signed certificate. Step4(a): Generate a private key. Please keep this key in /etc/httpd/conf/sslcrt #mkdir /etc/httpd/conf/sslcrt #cd /etc/httpd/conf/sslcrt.

Note: We can create this certificate key in any location but /etc/httpd/conf/sslcrt is good to remember. #openssl genrsa -des3 -out server.key 1024 Once we execute above command it will prompt for a new password as shown below Generating RSA private key, 1024 bit long modulus.++++++.++++++ e is 65537 (0x10001) Enter pass phrase for server.key: Verifying – Enter pass phrase for server.key: Just enter server key which is a password.

So remember this word. Let me explain the command openssl is the command to generate SSL certificate genrsa is to indicate generate a RSA key called server.key with des3 encryption with 1024 key lenght. To see the files create just give ls to check. #ls -lrt Step4(b): Now Generate a CSR (Certificate Signing Request) #openssl req -new -key server.key -out server.csr When you execute this command you will be prompted for number inputs as shown below. Enter pass phrase for server.key: You are about to be asked to enter information that will be incorporated Into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter ‘.’, the field will be left blank.

—– Country Name (2 letter code) [GB]:IN State or Province Name (full name) [Berkshire]:Andhra Pradesh Locality Name (eg, city) [Newbury]:Hyderabad Organization Name (eg, company) [My Company Ltd]:The Linux juggernaut Ltd. Organizational Unit Name (eg, section) []:IT Support Group Common Name (eg, your name or your server’s hostname) []:Surendra kumar Anne Email Address []: Please enter the following ‘extra’ attributes to be sent with your certificate request A challenge password []: An optional company name []: These are self learn entries. So you can give your own details. Just press enter at “A challenge password” and “An optional company name” Don’t write anything for this two entries. To see the files which you have created just give ls to check. #ls -lrt Step4(c): Remove Passphrase from Key. Which not at all required and when ever Apache service is restarted your system will ask for this pass phrase.

In order to eliminate some one to sit in front of the system to enter the pass-phrase after a reboot or restart service or a crash we have to remove the pass-phrase as shown below. #cp server.key server.key.org #openssl rsa -in server.key.org -out server.key This will ask the pass-phrase for the last time.

Just enter the pass-phrase which you given. Step4(d): Now it’s time to generate a self-signed certificate. #openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt Once you execute above command you will get output as shown below Signature ok subject=/C=IN/ST=Andhra Pradesh/L=Hyderabad/O=The Linux juggernaut Ltd./OU=IT Support Group/CN=Surendra kumar Anne/ Getting Private key Subtask3: Step5: Create a normal AD account on your Domain controlar and assign a complex password for that one. Subtask4: Step5: Configure virtual host now in our httpd.conf file which is located at /etc/httpd/conf/ Step5(a): Specify NameVirtualHost NameVirtual Host server.linuxnix.com Step5(b): Specify ServerName as server.linuxnix.com in httpd.conf file ServerName server.linuxnix.com Step5(c): Now go to last line of the httpd.conf file and give below entries. AuthzLDAPAuthoritative off Prevent other authentication modules from authenticating the user if this one fails. Here it’s off so we are allowing if ldap authentication failed, apache will try other authentications too.

AuthLDAPBindDN “cn=test_apache,cn=Users,dc=linuxnix,dc=com” This is important line. Here AuthLDAPBindDN is saying what is the connecting account(here it’s test_apache ad account) and who are going to connect(cn=Users) and to which domain they are connecting(to linuxnix.com ie dc=linuxnix,dc=com) Note: If your domain ends with.co.in then connecting domain should be. Dc=linuxnix,dc=co,dc=in AuthLDAPBindPassword UV4Ziu6v This line provide the AD password(here it is UV4Ziu6v) for the user test_apache. So why we require this user name and password? Ans: We require this user name and password because this test user will try to contact the AD server for authenticating AD users. AuthLDAPURL “ldap://dc.linuxnix.com:3268/dc=linuxnix,dc=com?sAMAccountName?sub?(objectClass=*)” This line indicates where should my test_apache should connect to provide user authentications.

This line say that connect to dc.linuxnix.com on port 3268 with dc values as linuxnix.com. Require valid-users This line indicates that only valid users should be allowed to access this portal. Note:Some times we require to give access to perticular users then you can specify ldap-user variable as shown below. Required ldap-user surendra_anne suray_t meghana_bm When your Apache will see above line it will allow only surendra_anne, surya_t, meghana_bm to access to this portal.

And remaining AD users are denied to access this portal. Now save and exit the file Step6:Check for the syntax errors in the httpd.conf file before restarting the Apache service. #httpd -t or #httpd -k graceful Step7: Now start the service and then add it to booting scripts so that it will start automatically at every boot of the system #service httpd restart #chkconfig httpd on Step8: Now try to access you will be prompted to enter AD user-name and password.

Hello, this is my first post but I have been a lurker for a long time. I saw your thread and felt your pain as I had a very similar issue that I was able to work out through trial and error. Based on your photo you are using for ldap?

This is what worked for me so I hope it works for you: •Trying pinging the ip address of your ldap server from your linux server, this is just to make sure you can see it, if you don’t get a ping back then double check your network settings. If you get a ping back then proceed to the following steps. •First thing you should do is remove your server connections to ldap and then disable the app and start over.

•Once you re-enable the app just put in your server ip address to the “Host” line (if using ssl then put ) don’t put in the port number but instead click on “Detect Port” it may take a minute or 2 but if your network connections on your server are setup correctly it should fine your port automatically. If it finds your port then you are making progress, but if it doesn’t find your port check your network settings. •Ensure you have the correct “User DN” path and that you have the correct user name, if the name has spaces ensure it looks identical to the ldap name. •Enter the password you assigned the user; I would test you can logon with the user through a PC just to ensure you have the name and password correct. I know it sounds silly but just make sure. •If you can logon to a computer on your domain with the User name and password you are suing for this application then the next step is to click the “Detect Base DN” button and see if it detects your DN.

It should detect your DN if your above settings are correct. Then click on “Test Base DN” you will see a Red light or Green light indicating success or failure. Most times your Base DN will be the same ending of the User DN. •You shouldn’t have to make any other changes to the other tabs, but they should look similar to this: oUsers Tab: (&( (objectclass=person)(objectclass=user))( ( (memberof=CN=Cloud Group,OU=Group,DC=MyDomain,DC=int)(primaryGroupID=1230)))) oLogin Attributes: (&(&( (objectclass=person)(objectclass=user)))( (samaccountname=%uid)( (mailPrimaryAddress=%uid)(mail=%uid)))) oGroups Tab: Nothing in groups unless you created an LDAP group and put your users in there thus enabling Nextcloud access to select individuals. OAdvance Tab: Directory Settings: Should be filled out automatically by the detection process on step one, but if not then fill it out with your settings. OExpert Tab: The only thing I did here was add “samaccountname” to the UUID Attribute for Users field.

This makes it so your users name show up instead of their long numerical numbers. Hit test Configuration to ensure everything works correctly. Hope this Helps ~ wclang. Hi all, I have already solved it. I had problem in firewall rule between DC (Domain controller) and Nextcloud server (I installed the certificate to /etc/openldap/certs from DC, or you may disable verification of certificate, just add 'TLS_REQCERT never').

I had allowed only those ports (TCP 135, TCP 389, TPC 636, ICMP). So, l made firewall rule that allow all traffic (all TCP/UPD and ICMP) then I use 'Detect Base DN'. And it began to work! I was able load groups, users etc. So the detection procedure using some high TCP ( >1024). Then I went back default firewall rule and it still works.
