AIX

Hi all,

I have set up the AIX LDAP client on AIX 5.3.9 and it's working fine, using the descriptions in the Redbook for implementing LDAP in a heterogenous environment.
I added SSL encryption to the LDAP client demon's config and created a key-db and imported a signed certificate from our CA.

When I use ldapsearch with SSL and watch the traffic with tcpdump, everything is encrypted as it is supposed to be.
When issuing lsldap, the traffic is encrypted too.

When I try to login with an LDAP-only account, I can get on the system without problem, but the traffic is not encrypted at all. I can see in the tcpdump output everything uncrypted.

I tried a lot of different settings, but without success. Here is my current ldap.cfg:

Code:

serverschematype:rfc2307
ldapservers:10.10.10.10
binddn:cn=admin,o=services
bindpwd:{DESv2}somethingcryptedhere
authtype:ldap_auth
searchmode:OS
useSSL:yes
ldapsslport:636
ldapsslkeyf:/etc/security/ldap/key.kdb
ldapsslkeypwd:{DESv2}somethingcryptedhere
userclasses:posixaccount,account,shadowaccount
groupclasses:posixgroup
userattrmappath:/etc/security/ldap/2307user.map
groupattrmappath:/etc/security/ldap/2307group.map
userbasedn:ou=users,o=company,c=de
groupbasedn:ou=users,o=company,c=de
defaultentrylocation:LDAP

I can't see what I am missing or having setup wrong. I checked many sites about the topic but they all don't give more information than the Redbook already. Thanks a lot for any hint.

hm?

the ldap-encryption just encrypts the communication to the ldap-server, like authentication, user/group information, ldapsearch too of course

once you are on the machine, ldaps job is done, you need to use ssh/sftp to encrypt the whole datatransfer

edit: oh I guess you mean the login information is not encrypted?

I use almost the same setup with tivoli directory server, I'll see if it's not encrypted too on my aix systems, would be very bad if thats the case

That's just what it seems not to do when I do an ssh login with an LDAP based account. But I guess I found out what's going wrong, since there is a shell script being called doing an ldapsearch to sort out different loginshells based on ldapgroups etc.

Sorry for the noise, I found it.

ok so I don't have to analyse the tcpdump, hate that

you could close port 389 on your ldap-server, so there is no way to send unencrypted information

Hi,
I just got another question on LDAP over SSL:
On Linux you can configure in ldap.cfg with "TLS_REQCERT = allow" that any CA is accepted. Is there any option to do that on AIX? I checked all possible options /etc/security/ldap/ldap.cfg and didn't find one that might be similar to that mentioned above on Linux.

Goal is to bypass the CA certificates that expire in 2 years causing an update etc. on more than 100 servers. We want to have SSL encrypted communication for ldap (secldapclntd) and ldapsearch etc. while accepting every kind of certificate/CA.
