From 60bbc5034e546b7df7a6f782e3353b863f49618b Mon Sep 17 00:00:00 2001 From: Simo Sorce Date: Wed, 25 Feb 2009 19:36:43 -0500 Subject: Serialize access to sysdb and also exposes ldb transactions. This is necessary because in ldb only 1 transaction per context is possible and all operations (or new transactions) are nested within it. Will revisit this later when ldb will addresses the problem. --- server/responder/nss/nsssrv_cmd.c | 73 +++++++++++++++++++++++---------------- 1 file changed, 44 insertions(+), 29 deletions(-) (limited to 'server/responder/nss/nsssrv_cmd.c') diff --git a/server/responder/nss/nsssrv_cmd.c b/server/responder/nss/nsssrv_cmd.c index c61eb4f2..16146585 100644 --- a/server/responder/nss/nsssrv_cmd.c +++ b/server/responder/nss/nsssrv_cmd.c @@ -97,6 +97,9 @@ static int nss_parse_name(struct nss_dom_ctx *dctx, const char *fullname) char *delim;
