address already in use,說明已經有進程在偵聽對應的埠,你先將原來的進程kill掉再啟動下

你已經啟動slapd服務進程了.
你先service slapd stop,然後再slapd -d 256
《解決方案》
回復 4# chenyx
service slapd stop之後再slapd -d 256,相當於重啟了slapd服務。會卡停在slapd starting那裡,這時從另一個term中進入再測試slapd -d 256的結果和之前是一樣的。卡在slpad starting那裡最後我就ctrl+c停了。# slapd -d 256

那你為什麼不用service直接啟動呢?
ldap的服務配置你應該在配置文件裡面做好就可以的
《解決方案》
回復 6# chenyx
謝謝您的回復。
不過我現在的問題是服務可以啟動,可以添加用戶到ldap的db裡面,並且在authconfig裡面設置了用ldap登錄,但就是無法用ldap中的用戶登錄進來# ldapsearch -x -b "dc=tdi,dc=com"
# extended LDIF
#
# LDAPv3
# base <dc=tdi,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#
# tdi.com

dc: tdi
objectClass: top

# engineering, tdi.com

《解決方案》
你這種情況類似使用ctrl+z停止服務。重新啟動即可順速解決。也可以不用重新啟動解決。還是cheny說的殺進程。你應該沒有完全殺掉openldap的相關進程。數據庫使用的是bdb還是?
