Description: ------------ ** Caveat: I am not an LDAP, PHP or SASL expert, so I could be a long way off the mark here ** This is similar to bug 35611 (which is marked as Bogus!) and related to 30189, but I believe the problem is with authcid and not authzid. ldap_sasl_bind sends the binddn as the authcid, this behaviour differs to the standard ldapsearch etc utilities when using "-U" to send a username. This basically means that I cannot get it to bind to my ldap server, looking at the slapd debug it seems to send a username like... username="cn=My Name,ou=People,..." ... when I look at the debug from using an ldapsearch -U it gets a username="shortname" type output. By hacking the code to add another option (authcid) to the php ldap_sasl_bind function and sending that for the authcid instead of binddn everything works perfectly. A simple example is that you don't need to provide a BindDN to ldapsearch if you use -U, this is because the username will be mapped by the authz-regex to a real object. If you don't specify a binddn with PHP you get a "SASL bind in progress" error, and if you just specify a username then it fails with "invalid dn". (I can provide a very simple patch that fixes the problem if it helps) Reproduce code: --------------- See description above. Expected result: ---------------- See description above. Actual result: -------------- See description above. PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

Here is ldap_sasl_bind definition from http://www.php.net/manual/ru/function.ldap-sasl-bind.php: bool ldap_sasl_bind ( resource link [, string binddn [, string password [, string sasl_mech [, string sasl_realm [, string sasl_authz_id [, string props]]]]]] ) I've added authc_id argument to ldap_sasl_bind function into position of authz_id argument: bool ldap_sasl_bind ( resource link [, string binddn [, string password [, string sasl_mech [, string sasl_realm [, string sasl_authc_id [, string sasl_authz_id [, string props]]]]]]] ) phplpadadmin works fine after that! I use login_dn as "uid=username,ou=People,dc=example,dc=com". Phpldapadmin sets authz_id as "username". ldap_sasl_bind use that authz_id as authc_id. P.S. there similar bugs 35611 and 32055
