Actually I have the same syntax available in my slapd.access:
<who> ::= [ * | anonymous | users | self | dn[.<dnstyle>]=<DN> ]
[dnattr=<attrname>]
[group[/<objectclass>[/<attrname>]][.<style>]=<group>]
[peername[.<peernamestyle>]=<peer>] [sockname[.<style>]=<name>]
[domain[.<domainstyle>]=<domain>] [sockurl[.<style>]=<url>]
So probably the error is somewhere else. I report it again for the list
(sorry, I replied to Dieter only instead of the list the first time):
Checking configuration files for slurpd: /etc/openldap/userauth.acl:
line 82: group "cn=linuxa,ou=netgroup,dc=example,dc=com": inappropriate

(...)
Any hints?
Thanks again

Re: ppolicy - getting to work
by Prakash Velayutham
Thanks again. Makes sense.
Now that I am locked out for SSH access, I will just ask questions of
interest without actually trying things out. For all the different
ppolicy-related things to work, I am guessing the following is the
procedure. Please correct me.
a) Editing slapd.conf and adding "include", "modulepath", "loadmodule
ppolicy.la", "overlay", "ppolicy_use_lockout", "ppolicy_default"
statements.
b) Adding necessary policy-related objects to LDAP (policy object and
standard policy sub-object). These will inherit from pwdPolicy
objectclass.
c) Adding the users that will be managed by the password policy to the
directory. Do I have to add "objectClass=pwdPolicy" attribute to all the
users that need to be managed by ppolicy and leave it out for the other
users?
I will try all these out on monday.

Note that I build static modules, so this may need
verification/clarification, but I'll try:
The .la files are libtool archives. If you examine them (e.g. cat(1)),
then you'll see that they point to .so files (among other details). A
libtool-aware application--note that slapd(8) should be one of them--can
parse the .la file, which allegedly offers advantages (mostly platform
independence). So, following a 'make install', you should be able to
specify in slapd.conf
> moduleload /path/to/ppolicy.la
and that should parse OK. At least, that's the way I remember it...
Then again, you should be able to moduleload the .so also. If the .la
doesn't work out, try that.

Re: ppolicy - getting to work
by Prakash Velayutham
Thanks Aaron. So I built openldap with:
$ ./configure --with-tls=no --with-cyrus-sasl=no --enable-slurpd=no
--enable-ipv6=no --enable-ppolicy=mod --enable-hdb=yes --enable-modules
--enable-bdb=no --enable-ldif=no --enable-monitor=no --enable-relay=no
--enable-syncprov=no
Why do I have a ppolicy*.so and a ppolicy*.la file in the install
location? When do you use the ppolicy*.so?
I have temporarily lost access to the system because of PAM. Will have
access again on monday.

"yes" will build it into slapd, "mod" will give you a module. (You can
do
the same for --enable-hdb.)

Hello All,
I am trying to get ppolicy working on my openldap-2.3.29 server. I want
this setup to work with hdb backend and either static or dynamic ppolicy
module. What compile time options would be sufficient?

slapd + valsort using 100% CPU and causing slpad to become unresponsive
by Michael.Heep＠o2.com
Hello list,
I've been recently experimenting with the valsort overlay. After enabling
it on the servers in our test environment they became unresponsive after a
few minutes and a simple "top" showed a 100% cpu utilization on the
machines.
Before filing an ITS I thought I'd first post my problem here. Maybe it's
just something as simple as a misplaced configuration directive. Therefor
I've included the relevant information below.
The test-servers only have about 100 entries and usually no more than half
a dozen clients access them simultaneously.
OpenLDAP Version: 2.3.30
BerkeleyDB: 4.2.52 + 5 patches
OS: RHES 2.1 and 3.0

slow queries with long strings in filters
by Sylvain Amrani
Hi list,
I've got an attribute that could contains very long strings (more than
150 chr).
It's a string made of small tokens separated by spaces and slashes :
departmentUID: BA/BAC ANDL/BAPZ IDF/GRPT YVLN/CIE GN ST GERM...
The attibute is indexed with pres,eq,sub
When I search for small substrings like (departmentUID=*/GRPT*) it's
fast and ok.
When I search for a long subset of the string, the query is _very_ long
(many seconds) :
(departmentUID=BA/BAC ANDL/BAPZ IDF/GRPT YVLN/CIE GN ST*)
The more the string is long, the more the answer is slow.
I can use very complex filters (&((|()())(|()()))... and the answer is
very fast, unless I use a long string in it.
The backend is BDB (berkeley 4.2)
Openldap is 2.2.26
Is this a BDB or an Openldap related issue ?
Using subinitial or subany in the index slap.conf parameter did not
solve the problem.
I found only one post in the archives related to a server were any query
string with more than 3 characters makes slow answers. He was told to
adjust :
index_substr_if_minlen
index_substr_if_maxlen
index_substr_any_len
index_substr_any_step
But theses parameters are only available with openldap 2.3 and it
doesn't seem to be exactly my problem (I've no differences between 2,3,4
or 5 characters query strings)
Thanks,
Sylvain.

samba-computer record at OpenLdap
by Roman Yushin
Hello.
I have an old server with openldap-server-2.0.27_3 (+ samba schema),
samba-3.0.8,1 as PDC
All information stored at LDAP: domain-computers, domain-users
So, i have a record for computer:
dn: uid=ws01$,ou=People,o=campus,c=ru
uidNumber: 2000

I am commented lines "creatorsName, createTimestamp, modifiersName,
modifyTimestamp" and obtained ldiff-record to add it to another ldap server.
The problem is that i could not add domain-computers to new server with
openldap-server-2.3.30!
All users were added from old ldap to new, but i have a problem with
computers!
Here is the error

If i try to add this ldiff record at old openldap, it works fine.

ACL using netgroups
by Claudio Strizzolo
Hi all,
I'd like to set up an ACL which allows access to a subtree only to a
user, and only if the query is coming from a restricted set of hosts.
Up to now I've been doing this:
access to dn.subtree="ou=People,dc=example,dc=com"
by self read
by dn="cn=myuser,dc=example.com" \
peername.regex="10\.10\.10\.1[0-9]" read
by * none
This works.
However, the number of hosts to be allowed in this way is rapidly
increasing, and it is not easy to group their addresses in such a way to
make them easily summarized by a single regex, or a limited group of regexp.
Moreover, for other reasons I have grouped the hosts in a netgroup
inside the same database:
dn: cn=mynodes,ou=netgroup,dc=example,dc=com
objectClass: nisNetgroup
objectClass: top
cn: mynodes
nisNetgroupTriple: (node0.example.com,-,-)
nisNetgroupTriple: (node1.example.com,-,-)
(...)
nisNetgroupTriple: (node9.example.com,-,-)
My question is: is there any way to set the ACL above in such a way to
use this netgroup definition to limit access to the hosts listed in the
netgroup AND to the user as above, at the same time? I'm dreaming of
something like:
access to dn.subtree="ou=People,dc=example,dc=com"
by self read
by dn="cn=myuser,dc=example.com" \
netgroup="cn=mynodes,ou=netgroup,dc=example,dc=com" read
by * none
Any way to do something like this?
I beg your pardon if this is a stupid question, I'm just a LDAP beginner.
Thanks in advance
Claudio
