How to Verify the LDAP or slapd Process in Zimbra

Zimbra LDAP service running on OpenLDAP software. It is the directory service and identified when the Zimbra software is installed together with it’s own Zimbra schema. Zimbra LDAP service is used in Zimbra Collaboration Suite (ZCS) to store data for Zimbra Global configuration, user and authentication information, server, domain and class of service (COS) details. The following task will be very useful to zimbra system administrator in order to Verify the LDAP or slapd process in Zimbra. The command has been tested on ZCS 8.0.4 open-source version running on CentOS 6.4. I have documented these post as my own tutorial and also for my blog visitors reference. 1. How to verify ldap status in zimbra. Run as the zimbra user :

[zimbra@centos64 ~]$ ldap status
slapd running pid: 1351

2. How to verify that the slapd process is running or not :

ps auxww | grep zimbra | grep slapd

Example :

[zimbra@centos64 ~]$ ps auxww | grep zimbra | grep slapd
zimbra    1351  0.1  3.9 18840944 75268 ?      Ssl  16:44   0:08 /opt/zimbra/openldap/sbin/slapd -l LOCAL0 -u zimbra -h ldap://centos64.ehowstuff.local:389 ldapi:/// -F /opt/zimbra/data/ldap/config
zimbra   42865  0.0  0.0   6376   724 pts/0    S+   18:01   0:00 grep slapd

3. To detect connection failure on default ldap port, 389, run telnet command :
Result if run from zimbra server itself :

[zimbra@centos64 ~]$ telnet centos64.ehowstuff.local 389
Trying 192.168.2.62...
Connected to centos64.ehowstuff.local.
Escape character is '^]'.
^]
telnet> quit
Connection closed.

4. How to Stop and Start ldap in zimbra. Run as the zimbra user :
Start ldap :

[zimbra@centos64 ~]$ ldap stop
Killing slapd with pid 1351 done.

Stop ldap :

[zimbra@centos64 ~]$ ldap start
Started slapd: pid 47807

5. Verify ldap status from zmcontrol command :

[zimbra@centos64 ~]$ zmcontrol status
