adding entries in ldap

hi,

i need add certain entries in ldap.
for eg: am adding mail.com.ldif file in ldap
which consists of

dn: uid=saurav,ou=solution,dc=linux,dc=com
cn: Manaager
sn: ganguly
uid: saurav
mail: saurav@linux.com
description: Indian Team
telephoneNumber: 012101012
userPassword: password
uidNumber: 1023
gidNumber: 10023
objectClass: person
objectClass: top
objectClass: inetOrgperson
objectClass: posixAccount

In this i had mentioned uid,cn,sn and mail address,password and objectclasses for these attributes.

I need to mention my mailbox location,so that when i send mail from client such as outlook, mail will go to mailserver look ldap directory get the user mailaddress and mailbox location and deliver the mail in that location.

For specifying the mailbox location what is the attribute name that i have to mention?
And tell me objectclass for that atribute.

You should use the objectClass that matches your mail-server. For example for my qmail installation I have:

Code:

...
objectClass: qmailUser
mailMessageStore: /var/qmail/maildirs/user
mailHost: smtp.example.com
mail: user@example.com
...

hi,

so as you said, am using postfix mailserver so i have mention like this write,

...
objectClass: postfixUser
mailMessageStore: /var/postfix/maildirs/user
mailHost: smtp.linux.com
mail: user@linux.com
...

I had tried this to but still getting the same error,

[root@experts ~]# ldapadd -x -D "cn=Manager,dc=linux,dc=com" -W -f /etc/openldap/mail4.com.ldif
Enter LDAP Password:
adding new entry "uid=saurav,ou=solution,dc=linux,dc=com"
ldapadd: Undefined attribute type (17)
additional info: mailMessageStore: attribute type undefined

This is my mail4.com.ldif file

dn: uid=saurav,ou=solution,dc=linux,dc=com
cn: Manager
sn: ganguly
uid: saurav
mail: saurav@linux.com
mailbox: /var/spool/mail/saurav
description: Indian Team
telephoneNumber: 012101012
userPassword: password
uidNumber: 1023
homeDirectory: /var/spool/mail/saurav
gidNumber: 10023
objectClass: person
objectClass: top
objectClass: inetOrgperson
objectClass: posixAccount
objectClass: organizationalPerson
objectClass: postfixUser

qmail provide their own schema for ldap

See http://ldapadmin.sourceforge.net/docs/introduction.html for postfix reference, or do a google for "postfix ldap schema"

It's not that simple.
You should find the postfix schema file (for example postfix.schema), copy it under /etc/openldap/schema/ and add the entry for it in slapd.conf under the other schema entries, e.g:

Code:

include /etc/openldap/schema/core.schema
include /etc/openldap/schema/cosine.schema
include /etc/openldap/schema/inetorgperson.schema
include /etc/openldap/schema/nis.schema
include /etc/openldap/schema/postfix.schema

Then you should use the mail attributes provided by that schema for your users.

***EDIT***
Just saw billymayday's answer about postfix.schema. Follow the link provided and near the end you'll find a postfix.schema file.

Please note the point of my post is that there doesn't seem to be a specif postfix schema

aravind1024004 · 04-17-2008, 05:06 AM

hi,

In postfix there is a schema called misc.schema but it was not mentioned in slapd.conf file, but it was in schema directory.
In that misc.schema attributes like mailHost are available.

So i added this attribute in slapd.conf like

include /etc/openldap/schema/misc.schema

But still getting the same error.But mailHost attribute is exists in misc.schema file.

Here am integrating postfix with openldap.
In ldap ldif file i will add the user information like

mailaddress,password,mailbox location,mailserver domain etc

When i send mail from client it must want to get the information from ldap database and the mail must want to deliver to the mailbox location which i mentioned in ldap database.

I need to whether the users must want to exists in mailserver for creating mailbox.
In my setup i simply created the mailbox location without creating the user.

for eg: i didnt create a user called saurav in my mailserver,but i created a mailbox location for the user saurav in

/var/spool/mail/saurav and gave the write permission for this file.

When i send mail from my client it checks the ldap database,get the user information for saurav and delivering error that user unknown in local recipien table.

If i want to create the user in my mailserver then whats the use of ldap database here?

billymayday · 04-17-2008, 05:22 AM

You can only use attributes that are included in objectclasees, etc. You probably need to to a little basic research on ldap

aravind1024004 · 04-17-2008, 05:29 AM

Ok what is the solution for that user account in mailserver,
whether for creating mailbox in mailserver user is required?
if yes then whats the use of LDAP?
plz be detail in your answer

The user must exist in your ldap database, in order to be able to receive mail. Whenever an e-mail arrives, postfix will search ldap database and if it finds that user it will deliver the mail to the specified mailbox, else it discards it.
To add a mail user in ldap, you must give him the appropriate attributes, that it turn depend on specific objectclasses that are defined in specific schema files.
