I configured my client to use ldap for hosts in /etc/nsswitch.conf. Its using ldap for host lookups only, nothing else. The client works fine, it can find the 2 hosts in ldap. If I try to telnet from a host not in ldap it works but if I try to telnet from one of the hosts in ldap to my client, it hangs. If I set binddn on the client, then the hosts in ldap can telnet to the client but the client can't lookup host names. I'm new to ldap so I'm not sure if this is a pam or ldap issue. I don't understand why enabling the binddn allows the remote host to telnet but breaks local name lookups. Thanks -- Eric Ritchie Interactive Brokers LLC 203-618-5868

Re: OpenLDAP Group ACL
by Luke Lee 28 Mar '08

Sir, I modified my settings and added the following group: dn: cn=pwmanager,ou=Group,dc=mydomain,dc=com objectClass: posixGroup objectClass: top cn: pwmanager userPassword: {crypt}x gidNumber: 550 memberUid: l_luke memberUid: w_smith I also modified my ACL in the slapd.conf: access to attr=userPassword by self write by anonymous auth by group/groupOfNames/member="cn=pwmanager,ou=Group,dc=mydomain,dc=com" write by * none access to * by self write by group/groupOfNames/member="cn=pwmanager,ou=Group,dc=mydomain,dc=com" write by * read I used the same command trying to change the user's password but received the exact same error. Would you please help? You mentioned that the nisNetgroup object doesn't fit in the ACL configuration in your previous reply. I had defined netgroups looked like the following: dn: cn=Sales,ou=Netgroup,dc=mydomain,dc=com objectClass: nisNetgroup objectClass: top cn: Sales nisNetgroupTriple: (,c_parks,mydomain.com) nisNetgroupTriple: (,j_berryhill,mydomain.com) nisNetgroupTriple: (,b_chen,mydomain.com) Would there be a way for me to use the netgroup and its members for any ACL type of access?

Thanks! As indicated in slapd.access(5), the member attribute must have either distinguishedName syntax (or nameAndOptionalUID syntax) or be derivated from memberURL; it defaults to "member". It appears from your message that you expect "nisNetgroupTriple" to be used as member attribute, but you should specify that attribute in the ACL clause. However, "nisNetgroupTriple" wouldn't be allowed since it doesn't comply with the above restrictions. You need to use LDAP groups for access control; nisNetGroup objects don't fit. p. Ing.

OpenLDAP Group ACL
by Luke Lee 27 Mar '08

Hello, I'll appreciate it if any of you are willing to take time and share with me your experience with OpenLDAP running on a RedHat server configured with group ACL.

ways to connect to IBM Lotus Directory
by Ildar Mulyukov 27 Mar '08

27 Mar '08

Hello, I want to replicate an IBM Lotus Directory version 8 to my OpenLDAP server. Does anyone have such an experience? Anyone to give me a good advice? Thank you. I was thinking of several questions: 1. I need IBM attributes, objectClasses etc. to use as an additional OpenLDAP schema. 1a. Is it possible to create a schema file using LDAP schema discovery? 2. Is Syncrepl of any use here? 3. As a last resort I could use ldapsearch+ldapadd as soon as I get Lotus schema. Thanks for any help.

NIS to ldap layout
by Eric Ritchie 24 Mar '08

24 Mar '08

I have 3 NIS domains I wish to convert to ldap. I would like to keep 3 separate areas in ldap since the NIS domains have different accounts. I created a base dn and loaded data under 3 higher levels, such as base is dc=xyz,dc=com and dc=a,dc=xyz,dc=com dc=b,dc=xyz,dc=com dc=c,dc=xyz,dc=com. Then if I want client one to be in domain a, I set its base to dc=a,dc=xyz,dc=com. This works for host name lookups but when another host tries to login to the box via telnet or rsh, the login hangs after the password is entered, ssh works though. If I specify a binddn on the client with dc=a,dc=xyz,dc=com, I can login via telnet and rsh but name lookups fail on the host. Any idea what is causing this? Is this the best way to have separate DBs for clients? Thanks -- Eric Ritchie Interactive Brokers LLC 203-618-5868

Hi, I've configured ldap translucent overlay with slapd-ldap as backend. Then I changed userPassword of a user. When I try to auth to the translucent server, the new password is not valid, and I have to introduce the password that be in ldap server which is being proxied. I would like new password would be the password used for auth. Do you know how could I configure such approach ? Thank you in advanced
