Smile Migration Of Users From Linux-Fedora To LDAP server!

Dear All Openldap USERS,

This is Jyotishmaan Ray, from Silchar, India.

I have been working on migration of users from fedora-linux server to LDAP server. Of late after i have migrated all users, as per the administration guide of openldap sofware, i realised that i have done something wrong, because of which the authentication is not successfully happening.

Attention please, all openldap experts who are on linux-fedora platform please give you kind attention to my questions:-


1) Is it necessary to execute the following steps :-

Now you are ready to migrate the data (actually it works even without the export command):

export ETC_SHADOW=/etc/shadow
./migrate_base.pl > /tmp/base.ldif
./migrate_group.pl /etc/group /tmp/group.ldif
./migrate_hosts.pl /etc/hosts /tmp/hosts.ldif
./migrate_passwd.pl /etc/passwd /tmp/passwd.ldif

Now we have the data in the format understood by LDAP server. Please open one the files with text editor to get used to the syntax. After that we can add the data from ldifs.

ldapadd -D "cn=Manager,dc=domain,dc=com" -W -f /tmp/base.ldif

ldapadd -D "cn=Manager,dc=domain,dc=com" -W -f /tmp/group.ldif

ldapadd -D "cn=Manager,dc=domain,dc=com" -W -f /tmp/passwd.ldif

ldapadd -D "cn=Manager,dc=domain,dc=com" -W -f /tmp/hosts.ldif


However, i have not performed all the above steps except for the addition of users(ldif files after converting by using perl script)!!


As of now, when i finger the users, it shows fine. But when i try to log ion to the server machine using

ssh localhost.localdomain. -l xyx,

or

ssh "hostname" -l xyz


it prompted me the password twice one trial after another and subsequently throwing the message as shown below:-


[root@authdns bin]# ssh authdns.nits.ac.in -l jmaan
jmaan@authdns.nits.ac.in's password:
Permission denied, please try again.
jmaan@authdns.nits.ac.in's password:
Permission denied, please try again.
jmaan@authdns.nits.ac.in's password:
Permission denied (publickey,gssapi-with-mic,password).
[root@authdns bin]#




After seaching on the google.co.in, i have changed the default permission of the file /dev/tty (666) to 777.


Still it is not successfully working with ssh. I just wanted to make it sure that i could log in with user locally, to my server. However, the /etc/passwd file does not show the passwd field of the users as 'x' but rather as '*'.


To check this i have tried using the command,


getent passwd|grep user


it worked fine.


Please tell me is it because i have not performed the first few steps of ldapadd of (locals machine's) base.ldif, hosts.ldif, group.ldif to the ldap server that, its not working.


I have also worked with the command:-


pwconv



to generate the new shadow file from the /etc/passwd file.


Please help!!
