Hello,
We are students of College of Engineering, Pune and are setting up our
labs with Ubuntu 8.10 with LDAP (i.e. Allocating User accounts to
every student in the department). We also need to integrate this with
the Moodle that has been set up.
We had tried this previously, but due to some technical difficulties
we had to restart our work.
Now, the problem that we are facing is, of PASSWORD CHANGED.
What we have done :
- Softwares Installed Successfully on Ubuntu 8.10:
Bekerley DB db-4.7.25
OpenLDAP openldap-2.4.16 Stable Release
- Created and added hierarchy.ldif, group and all useraccount files to
slapd
- Configured LDAP Clients with libnss-ldap and LDAP Version 3
Here are some of the config. files
1. /etc/ldap/ldap.conf
base dc=coep,dc=org,dc=in
uri ldap://10.1.11.48
2. /etc/pam.d/common-account
account required pam_unix.so
broken_shadow
account sufficient
pam_succeed_if.so uid < 500 quiet
account [default=bad success=ok
user_unknown=ignore] pam_ldap.so
account required pam_permit.so
3. /etc/pam.d/common-auth
auth required pam_env.so
auth sufficient pam_unix.so
nullok try_first_pass
auth requisite
pam_succeed_if.so uid >=500 quiet
auth sufficient pam_ldap.so
use_first_pass
auth required pam_deny.so
4. /etc/pam.d/common-password
password requisite
pam_cracklib.so try_first_pass retry=3
password sufficient
pam_unix.so md5 shadow nullok
try_first_pass use_authtok
password sufficient
pam_ldap.so use_authtok
password required
pam_deny.so
5. /etc/pam.d/common-session
session required pam_limits.so
session [success=1 default=ignore]
pam_succeed_if.so service in
crond quiet use_uid
session required pam_unix.so
session optional pam_ldap.so
6. /etc/nsswitch.conf
passwd: compat files ldap
group: compat files ldap
shadow: compat files ldap
hosts: files mdns4_minimal
[NOTFOUND=return] dns mdns4
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis
- The user logins are successful, but when we try to change the
password of the user using the 'passwd' command, the following error
occurs,
passwd: Module is unknown
passwd: password unchanged
We need to allow users change their passwords, by some means, because
these same accounts will also be working with Moodle.
Tried searching a lot over the net, but didnt find required
solutions. Kindly Help us in this.
