Blank Password for a ldap user
by Rocky S 01 Apr '08

01 Apr '08

I am very new ldap programming, so bear with me if my query is naive. I am trying to write a program using the OpenLDAP SDK. The program should take an LDAP servername/port, a CN & a password. The program should then report if the CN/password combination is correct or incorrect. This is how I am trying to do this. [ error checks removed for making it simple] LDAP *pldap; ldap_initialize(&pldap, "ldap://myhost:389) ; int desired_version = LDAP_VERSION3; ldap_set_option(pldap, LDAP_OPT_PROTOCOL_VERSION, &desired_version); int ret = ldap_bind_s(pldap, "uid=Jack,ou=People,dc=vss,dc=veritas,dc=com", "jack123", LDAP_AUTH_SIMPLE); if(ret == LDAP_SUCCESS) puts("VERIFIED"); else puts("FAILURE"); This works fine for for Jack/jack123. I have another user in the directory - John who has a null/empty password I tried both ldap_bind_s(pldap, "uid=John,ou=People,dc=vss,dc=veritas,dc=com", NULL, LDAP_AUTH_SIMPLE); ldap_bind_s(pldap, "uid=John,ou=People,dc=vss,dc=veritas,dc=com", "", LDAP_AUTH_SIMPLE); Both cases ldap_bind_s returns 53 - which I think means LDAP UNWILLING TO PERFORM I know the server allows null passwords.

logs and I/O Performances
by Andre Stoffel 31 Mar '08

31 Mar '08

Hi all, We are using 3 LDAP Directories based on Openldap 2.2.23 (number of objects : between 4000 and 11000 in the DBs) . The hardware is based on HP servers correctly dimensioned but not oversized disks resided on an EMC Symmetrix We try to implement the ldap logs but we have to stop after the first test: a common request taking between 1 up to 2 seconds instead of some milliseconds. Has anybody an idea of whats going wrong: setting, architecture Thanks. André.

OpenLDAP as a Meta directory for eDirectory and Active Directory
by Jon Gerdes 30 Mar '08

30 Mar '08

I have a requirement to link up the contents of an AD and an eDir into a single meta dir. I am testing all this on a small system. The basic idea is that a user will be able to do a search on their uid and then bind to it. Their account could be in either the AD or the eDir. I would want to support both simple and digest-md5 binds. Both eDir and AD support SASL digest md5 binds but AD does not allow simple binds. I do not wish to change the back ends but just work with what is there. In my test system I have dc=blueloop,dc=net at the top with ou=edir and ou=ad to be mapped under the top level. My gerdesj account has all the relavent rights in all cases. I have gone around in circles on this several times! I can do a browse of the edir container fine ie a search of the ou=edir,dc=blueloop,dc=net as anon returns stuff as I would expect. This seems to work OK: ldapsearch -h localhost '(objectclass=*)' -D "cn=gerdesj,ou=edir,dc=blueloop,dc=net" -b "ou=edir,dc=blueloop,dc=net" -x -W Trying to use SASL fails: ldapsearch -h localhost -b 'ou=edir,dc=blueloop,dc=net' '(objectclass=*)' -Y DIGEST-MD5 -U "dn:cn=gerdesj,ou=edir,dc=blueloop,dc=net" SASL/DIGEST-MD5 authentication started Please enter your password: ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: SASL(-13): user not found: no secret in database This seems to imply to me that the OpenLDAP box is trying to auth me rather than passing this off to the system it is proxying. Why ? I would also like to make the AD side of things such that it will allow a simple anonymous connection to search and then allow through a simple bind I've read everything I can find but have run out of steam. Thanks for any advice or pointers. Cheers Jon Here is a chunk out of my slapd.conf ##### eDir #ldapsearch -h localhost -b 'ou=edir,dc=blueloop,dc=net' -s sub -x -D '' '(objectclass=*)' database ldap suffix "ou=edir,dc=blueloop,dc=net" uri "ldap://port.blueloop.net/" subordinate overlay rwm rwm-suffixmassage "ou=edir,dc=blueloop,dc=net" "ou=users,o=blueloop" ##### AD database ldap suffix "ou=ad,dc=blueloop,dc=net" uri "ldap://baileys.blueloop.net/" subordinate idassert-authzFrom "dn:regex=.*" acl-bind bindmethod=sasl saslmech=DIGEST-MD5 authcId=gerdesj authzId=gerdesj credentials="{SSHA}xxxxxx" idassert-bind bindmethod=sasl saslmech=DIGEST-MD5 binddn="cn=gerdesj,ou=users,ou=blueloop,dc=blueloop,dc=net" credentials="{SSHA}xxxxxxxxxxxxxx" mode=self overerlay rwm rwm-suffixmassage "ou=ad,dc=blueloop,dc=net" "ou=users,ou=blueloop,dc=blueloop,dc=net" Registered Address : 7 Manor Buildings, North Perrott, Crewkerne, Somerset, TA18 7ST Registered England & Wales - 3981322 CONFIDENTIAL INFORMATION This e-mail and any files attached with it are confidential and for the sole use of the intended recipient(s).

Unable to add attribute to cn
by Frank, Hans, 232 28 Mar '08

28 Mar '08

Hi there, I would like to add the attribute "orclnetdescstring" to the following ldap object: cn=TESTDB,cn=OracleContext,dc=test,dc=de When trying this, I get the following error message: 09:44:42 AM: Failed to add 'orclnetdescstring' attribute for ldap://***:389/cn=TESTDB,cn=OracleContext,dc=test,dc=de Root error: [LDAP: error code 65 - attribute 'orclnetdescstring' not allowed] I did include the attributetype into the core.schema, which is included in slapd.conf the following way: attributetype ( 1.3.6.1.4.1.9232.6 NAME 'orclnetdescstring' DESC 'Oracle-OID spezific A-Type' SUP name ) or: attributetype ( 1.3.6.1.4.1.9232.6 NAME 'orclnetdescstring' SUP name ) But that doesn't change anything. I am very new to openldap, so if there are any good tutorials which describe such simple things (I suppose this is something simple), please let me know. I just need this object with some specific attributes, how can I realise this? Best Regards Hans Frank

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

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.
