Is back-sql production ready ?
by Mike Bloom 03 Nov '06

03 Nov '06

Hi, I've been using ldap for a few years now, but I've come to the realization that I have a lot of mysql databases lying around that should be integrated and unified. Its time to move to something more robust. I'm using openldap-24 and am thrilled with the responsiveness and extensibility of the software, but I'm curious about using mysql as a back end instead of bdb. I've been able get unixODBC up and running without any problems, but I'm stumbling a bit over the 10,000 foot view on metadata and how to generate metadata to insert a samba 3 object. After skimming for a few days, I found this lovely overview (http://www.openldap.org/faq/data/cache/978.html) which didn't inspire a lot of confidence in how easy it would be to support abstract schemas that we might want to host on this system. From this discussion and subsequent threads (http://www.openldap.org/lists/openldap-software/200511/msg00504.html) , I'm concerns about the practicality and that I might have unrealistic expectations for being able to deploy 250k records on my mysql cluster to service a series of ldap servers over back-sql. Does anyone run back-sql in production, and what kind of records on what scale of system are you using ? I have high confidence that I want to use ldap, but I'd rather right provisioning software that talks to a mysql database than to talk to the ldap database. To make things more complicated, I suspect we will be moving to oracle in the next few years. Does anyone have any suggestions on a 10000 foot view of metadata ? Thanks.

posixgroup & structuralobject errors
by jef peeraer 03 Nov '06

03 Nov '06

i am using openldap for many years now ( arround 300 users ) but recently i encountered some problems. i installed a new server ( opensuse 10.1) and tried to import an ldap database which comes from a suse 9.3 There seems to be a difference in schemas anyway. (opensuse 10.1 has openldap version 2.3.19 , 9.3 -> 2.2.23) I've get these errors during import -> structuralObjectClass 'posixGroup' is not STRUCTURAL The entry on which i've got the complaints -> dn: cn=root,ou=Group,dc=deterp,dc=be objectClass: posixGroup objectClass: top cn: root userPassword:: xxxxxxx gidNumber: 0 structuralObjectClass: posixGroup I did a search in the faq and on google, but didn't find very much about it. jef peeraer

Hello, I am new to openldap and am having trouble with ldapadd. This is the error I am getting when running the command.

ppolicy implementation questions
by Lee Sheridan 02 Nov '06

02 Nov '06

I'm a little confused about a couple of things with ppolicy, I would appreciate somone helping me to sort it out. Here's my problem. I have a pwdMinAge set to some number X. The reason is that the password policy I'm implementing says that passwords must not be reused until some N days and Y number of changes have elapsed. Thus, pwdMinAge is approximately N / Y, which means that even if a user changes their password every X days, they won't go through all Y passwords until all N days have passed. Clearly not the best option. So my first question is this: I see that the pwdHistory attribute stores time the password was used within it. Is there some way for ppolicy to check if a password that is being reused has been reused in < X days? Failing in that (which would allow me to get rid of using pwdMinAge)... When I set a user password with the rootdn or similar, the user can not reset their password because it is too young. I can see no way to modify pwdChangedTime. How exactly is this handled? Third, apparently only the rootdn can set a password when the password is < pwdMinAge. Users with an ACL that allows write access to userPassword also go through the ppolicy policies (which makes sense). Is there a way to exclude them also from ppolicy constraints when setting another user's password?

2.3 admin guide
by Gerard Ranke 02 Nov '06

02 Nov '06

Hi all, I wanted to read up on indexing, and I noticed that, in the admin guide, the index directive is under par. 6.2.5.6. So it seems as if this is specific to the ldbm backend ( par. 6.2.5 ). I was under the impression that index directives were valid for bdb backends too. So, can I use index directives for bdb? And is the syntax in 6.2.5.6 still valid? Thanks for your answers. Best regards, Gerard Ranke

ldapsearch hang
by Phillip 02 Nov '06

02 Nov '06

Hi all, I do the following testing, use a running "ftp" to instead of existed LDAP, and with its corresponding port, # ldapsearch -x -H ldap://192.168.123.1:22 Here, 192.168.123.1 is a ftp server with port 22 open. When I execute the command, it seems to be hung without any error messages. I think, if the ldap server or port is not available, it would return with error message immediately. How do you think of this interesting testing? Regards, Phillip

slapo accesslog purge in 2.3.19 [auf Viren überprüft]
by Hans Moser 02 Nov '06

02 Nov '06

Hi! I activated overlay accesslog in a 2.3.19 server. Everthing works fine (changes are logged) as long as I do not activate logpurge: line 69 (overlay accesslog) line 70 (logdb "ou=log,ou=foo,o=bar,c=de") >>> dnPrettyNormal: <ou=log,ou=foo,o=bar,c=de> <<< dnPrettyNormal: <ou=log,ou=foo,o=bar,c=de>, <ou=log,ou=foo,o=bar,c=de> line 71 (logops writes) line 72 (logpurge 10+00:00 1+00:00) /opt/mail//etc/openldap/slapd.conf: line 72: <logpurge> handler exited with 1! slapd destroy: freeing system resources. slapd stopped. connections_destroy: nothing to destroy. # in slapd.conf overlay accesslog logdb "ou=log,ou=foo,o=bar,c=de" logops writes logpurge 10+00:00 1+00:00 This seems not to be related to ITS#4505 or #4595, which occour in CHANGES for "accesslog purge" for version >2.3.19.
