#33588 [NEW]: No RootDSE query possible

From: cajus at naasa dot net Operating system: Debian GNU/Linux PHP version: 5.0.4 PHP Bug Type: LDAP related Bug description: No RootDSE query possible Description: ------------ I've found that searching the RootDSE does not work with PHP, because the base is set to NULL when no base is specified. This fact causes the LDAP library to look into the systems ldap.conf to take the base from there - which is probably not what we want. The following patch fixes the problem: --- php5-5.0.4/ext/ldap/ldap.c 2005-01-19 01:27:42.000000000 +0100 +++ php5-5.0.4/ext/ldap/ldap.c.fixed 2005-07-01 17:15:55.000000000 +0200 @@ -575,6 +575,7 @@ { zval **link, **base_dn, **filter, **attrs, **attr, **attrsonly, **sizelimit, **timelimit, **deref; char *ldap_base_dn = NULL; + char *dummy_base_dn = ""; char *ldap_filter = NULL; char **ldap_attrs = NULL; ldap_linkdata *ld; @@ -674,7 +675,7 @@ } else { nbases = 0; /* this means string, not array */ convert_to_string_ex(base_dn); - ldap_base_dn = Z_STRLEN_PP(base_dn) < 1 ?
