From 1e0f445f123f3ee96260989895f3ba558697d152 Mon Sep 17 00:00:00 2001 From: Stephen Gallagher Date: Wed, 11 Feb 2009 12:08:09 -0500 Subject: Add sysdb_add_group_to_posix_group, refactored sysdb_add_acct_to_posix_group to now use sysdb_add_member_to_posix_group along with sysdb_add_member_to_posix_group. Added new unit tests to sysdb-tests.c for groups of groups. --- server/db/sysdb.c | 145 ++++++++++++++++++-------------------- server/db/sysdb.h | 11 +++ server/tests/sysdb-tests.c | 172 ++++++++++++++++++++++++++++++++++++++++----- 3 files changed, 236 insertions(+), 92 deletions(-) (limited to 'server') diff --git a/server/db/sysdb.c b/server/db/sysdb.c index 175bf5458..edf3593f7 100644 --- a/server/db/sysdb.c +++ b/server/db/sysdb.c @@ -1263,24 +1263,21 @@ done: return ret; } +/* Wrapper around adding a user account to a POSIX group */ int sysdb_add_acct_to_posix_group(TALLOC_CTX *mem_ctx, struct sysdb_ctx *sysdb, const char *domain, - const char *gname, + const char *group, const char *username) { TALLOC_CTX *tmp_ctx; - int ret, lret; + int ret; char *account; struct ldb_dn *acct_dn; struct ldb_dn *group_dn; - struct ldb_message *msg; - struct ldb_result *res; - struct ldb_request *req; - const char *acct_attrs[] = { SYSDB_PW_NAME, NULL }; - const char *group_attrs[] = { SYSDB_GR_MEMBER, NULL }; - if (!sysdb || !domain || !gname || !username) { + + if (!sysdb || !domain || !group || !username) { return EINVAL; } @@ -1292,88 +1289,86 @@ int sysdb_add_acct_to_posix_group(TALLOC_CTX *mem_ctx, account = talloc_asprintf(tmp_ctx, SYSDB_PW_NAME"=%s,"SYSDB_TMPL_USER_BASE, username, domain); - if (account == NULL) { - talloc_free(tmp_ctx); - return ENOMEM; - } + if (account == NULL) goto done; + acct_dn = ldb_dn_new_fmt(tmp_ctx, sysdb->ldb, account); - if (acct_dn == NULL) { - talloc_free(tmp_ctx); - return ENOMEM; - } + if (acct_dn == NULL) goto done; group_dn = ldb_dn_new_fmt(tmp_ctx, sysdb->ldb, SYSDB_GR_NAME"=%s,"SYSDB_TMPL_GROUP_BASE, - gname, domain); - if (group_dn == NULL) { - talloc_free(tmp_ctx); - return ENOMEM; - } - ret = EOK; + group, domain); + if (group_dn == NULL) goto done; - /* Start LDB Transaction */ - lret = ldb_transaction_start(sysdb->ldb); - if (lret != LDB_SUCCESS) { - DEBUG(1, ("Failed ldb transaction start !?
