[Issue 9293] New: slapo-ppolicy stores pwdGraceUseTime only with seconds
by openldap-its＠openldap.org 24 Feb '21

https://bugs.openldap.org/show_bug.cgi?id=9293 Issue ID: 9293 Summary: slapo-ppolicy stores pwdGraceUseTime only with seconds Product: OpenLDAP Version: 2.4.50 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: michael(a)stroeder.com Target Milestone: --- If password is expired slapo-ppolicy can return the number of grace logins for changing own password (graceAuthNsRemaining). slapd derives graceAuthNsRemaining from number of pwdGraceUseTime values. But those timestamps are only stored with a granularity of a second. Thus multiple grace logins are possible within a second without decremeting graceAuthNsRemaining value. This is unexpected and also leads to absurd work-arounds when writing automated tests like this: https://gitlab.com/ae-dir/python-ldap0/-/blob/master/tests/test_ppolicy.py#… Either a real Integer counter should be used or fraction of seconds should be used in pwdGraceUseTime values. This is a similar problem like pwdFailureTime solved in ITS#7161. -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=9205 Bug ID: 9205 Summary: Openldap 2.4.49 with overlays syncrepl+ppolicy+chain+ldap Product: OpenLDAP Version: 2.4.49 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: frederic.poisson(a)admin.gmessaging.net Target Milestone: --- Created attachment 700 --> https://bugs.openldap.org/attachment.cgi?id=700&action=edit test script copied from test022-ppolicy and modified to show the trouble Hello, I'm doing a OpenLDAP test with a master/slave replication configuration including ppolicy overlay. I would like to enable password change from the slave replica with chain overlay, in order to validate the ppolicy olcPPolicyForwardUpdates attribute to TRUE. I'm using LDAPS from slave to master with SASL External authentication with client certificate. The client certificate correspond to a user DN entry with "manage" rights on the master server (the same used for the replication). This user DN has authzTo attribute in order to match the correct PROXYAUTHZ request from its dn to user DN. All of this configuration works on replica when i do first a failed authentication (err=49) on replica. The pwdFailureTime value is updated on the DN entry from replica to slave normally. I'm also able to do after some self entry update on some attribute such as password or others from replica to master. But the weird behavior is that i need to run first an failed authentication, otherwise if i try to change attribute on the slave server, it respond an err=80 "Error: ldap_back_is_proxy_authz returned 0, misconfigured URI?". The only way to retrieve correct behavior is to restart slapd, and redo one failed authentication first. It seems that the chain overlay do not connect the master server at startup. I've done a modification of test script test022-ppolicy to test022-policy-chain which use the same LDIF source and show the problem of modification on the consumer not "relayed" to the supplier if a fail operation is not done before.

Both are considered to cause a segmentation fault because the value of the third parameter(*1) of test_filter is invalid. The third parameter(*1) of test_filter should be an address, like the source below. Excerpt from filterentry.c: -------------------- 60 int 61 test_filter( 62 Operation *op, 63 Entry *e, 64 Filter *f ) ** the third parameter of test_filter 65 { 66 int rc; 67 Debug( LDAP_DEBUG_FILTER, "=> test_filter\n", 0, 0, 0 ); 68 69 if ( f->f_choice & SLAPD_FILTER_UNDEFINED ) { ** referenced here 70 Debug( LDAP_DEBUG_FILTER, " UNDEFINED\n", 0, 0, 0 ); -------------------- Version-Release number of selected component (if applicable): How reproducible: Two times Steps to Reproduce: Unknown Actual results: slapd crashes with a segmentation fault and a core is outputted. Expected results: slapd doesn't crash and a core isn't outputted. Thanks! Simon -- You are receiving this mail because: You are on the CC list for the issue.

[Bug 9222] New: Fix presence list to use a btree instead of an AVL tree

https://bugs.openldap.org/show_bug.cgi?id=9222 Bug ID: 9222 Summary: Fix presence list to use a btree instead of an AVL tree Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- [23:34] <hyc> ok, so far heap profile shows that memory use during refresh is normal [23:35] <hyc> not wonderful, but normal. mem usage grows because we're recording the present list while receiving entries in the refresh [23:36] <hyc> I'm seeing for 1.2GB of data about 235MB of presentlist [23:36] <hyc> which is pretty awful, considering presentlist is just a list of UUIDs [23:36] <hyc> being stored in an avl tree [23:37] <hyc> a btree would have been better here, and we could just use an unsorted segmented array [23:42] <hyc> for the accumulation phase anyway. we need to be able to lookup records during the delete pphase [00:05] <hyc> this stuff seriously needs a rewrite [01:13] <hyc> 2.8M records x 16 bytes per uuid so this should be no more than 48MB of overhead [01:13] <hyc> and instead it's 3-400MB -- You are receiving this mail because: You are on the CC list for the bug.
