From 27c67307976a60088ca301e07404bdb52740c3af Mon Sep 17 00:00:00 2001 From: Jakub Hrozek Date: Fri, 15 Oct 2010 15:57:10 +0200 Subject: Use unsigned long for conversion to id_t We used strtol() on a number of places to convert into uid_t or gid_t from a string representation such as LDAP attribute, but on some platforms, unsigned long might be necessary to store big id_t values. This patch converts to using strtoul() instead. --- src/providers/ldap/ldap_id.c | 4 +-- src/providers/ldap/sdap_async_accounts.c | 46 ++++++++++---------------------- src/providers/proxy/proxy_id.c | 4 +-- src/util/find_uid.c | 8 +++--- 4 files changed, 22 insertions(+), 40 deletions(-) (limited to 'src') diff --git a/src/providers/ldap/ldap_id.c b/src/providers/ldap/ldap_id.c index be4642aa..135e3708 100644 --- a/src/providers/ldap/ldap_id.c +++ b/src/providers/ldap/ldap_id.c @@ -220,7 +220,7 @@ static void users_get_done(struct tevent_req *subreq) case BE_FILTER_IDNUM: errno = 0;
