Re: ldif invalid per syntax

Hey guys!

 Unfortunately I have a new wrinkle. While I certainly got to make my
sudoers work through LDAP (thanks to those who helped) unfortunately
PAM is unhappy at the moment.

 So, while sudo is working in ldap, for any of the services that need
to authenticate through pam (i.e. ssh and su) it is still a no-go. I
am getting pam authentication errors in my log files.

But LDAP is certainly doing it's job!

Using the account I have setup in LDAP as the pam user I can search my base DN:



[bluethundr@bluethundr-desktop:~ ] $:ldapsearch -x -h ldap -D
"cn=pam_ldap,ou=Services,dc=summitnjhome,dc=com" -w secret -b
"dc=summitnjhome,dc=com"
# extended LDIF
#
# LDAPv3
# base <dc=summitnjhome,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# summitnjhome.com
dn: dc=summitnjhome,dc=com
dc: summitnjhome
objectClass: dcObject
objectClass: organization
o: Summit NJ Home

# staff, summitnjhome.com
dn: ou=staff,dc=summitnjhome,dc=com
ou: staff
objectClass: organizationalUnit

# summitnjops, staff, summitnjhome.com
dn: ou=summitnjops,ou=staff,dc=summitnjhome,dc=com
ou: summitnjops
objectClass: organizationalUnit

# people, summitnjhome.com
dn: ou=people,dc=summitnjhome,dc=com
objectClass: organizationalUnit
ou: people

# Services, summitnjhome.com
dn: ou=Services,dc=summitnjhome,dc=com
ou: services
objectClass: organizationalUnit

# pam_ldap, Services, summitnjhome.com

sudoHost: ALL
sudoRunAsUser: ALL
sudoCommand: ALL
sudoOption: !authenticate

# search result
search: 2
result: 0 Success

# numResponses: 12
# numEntries: 11



And this is the entry I have in my LDAP database for the pam_ldap user:



5 cn=pam_ldap,ou=Services,dc=summitnjhome,dc=com
cn: pam_ldap
objectClass: top
objectClass: inetOrgPerson
sn: PAM
userPassword: secret


So far so good, everything works.

However, this is how I have my ldap.conf file setup:


host ldap.summitnjhome.com
base dc=summitnjhome,dc=com
binddn cn=pam_ldap,ou=Services,dc=summitnjhome,dc=com
bindpw secret
scope sub
pam_password exop
nss_base_passwd ou=staff,dc=summitnjhome,dc=com
nss_base_shadow ou=staff,dc=summitnjhome,dc=com


( I have also tried setting the host to 127.0.0.1 as well, with no joy)

And observe what happens if I try to su using pam/ldap


Oct  9 20:25:11 LCENT01 su: pam_ldap: error trying to bind (Invalid credentials)
Oct  9 20:25:11 LCENT01 su: pam_ldap: error trying to bind (Invalid credentials)
Oct  9 20:25:11 LCENT01 su: in _openpam_check_error_code():
pam_sm_acct_mgmt(): unexpected return value 11
Oct  9 20:25:11 LCENT01 su: bluethundr to root on /dev/pts/0



ssh has roughly the same effect on the logs but in order for me to
demonstrate that I would likely have to gain physical access to the
box to fix it. So hopefully the above example will suffice.

This is how my pam su file is configured:


LCENT01# cat /etc/pam.d/su
#
# System-wide defaults
#

# auth
auth            sufficient      pam_opie.so             no_warn no_fake_prompts
auth            requisite       pam_opieaccess.so       no_warn allow_local
#auth           sufficient      pam_krb5.so             no_warn try_first_pass
#auth           sufficient      pam_ssh.so              no_warn try_first_pass
auth            sufficient      pam_ldap.so
auth            required        pam_unix.so        no_warn try_first_pass nullok

# account
#account        required        pam_krb5.so
account         required        pam_login_access.so
account         sufficient      pam_ldap.so
account         required        pam_unix.so

# session
#session        optional        pam_ssh.so
session         required        pam_ldap.so
session         required        pam_lastlog.so          no_fail

# password
#password       sufficient      pam_krb5.so             no_warn try_first_pass
password        required        pam_unix.so             no_warn try_first_pass



I assume that whatever is breaking su is breaking ssh. Does anyone
have any ideas as to why slapd cannot access the pam_ldap account user
automatically through /usr/local/etc/ldap.conf? x(
