Hi Vijay,

I haven't tried but refer to portal-impl\src\portal.properties where auth.simultaneous.logins=true. The comment says "This property is not used unless the property live.users.enabled is set to true" and by default live.users.enabled=false.

Make the following changes and see if it solves your problem.

Regards,
Raja

Hi Vijay,

AFAIK, Preventing user to login simultaneously is not available in Liferay 5.2.3. As neither portal.properties has "auth.simultaneous.logins=false" property nor LoginUtil.java has any code which prevent simultaneous login for Liferay 5.2.3

So if you need that in Liferay 5.2.3, you'll have to add it somehow by overriding existing code.

Thanks,
Tejas

Hi Tejas,

Thanks for your revert.

Appreciate if you can share any sample code which helps address this issue.

[Tejas Kanani，修改在10 年前。]

This is the code which exist in Liferay 6.1 -- LoginUtil.java -> login method, check it out it might help you.

		if (!PropsValues.AUTH_SIMULTANEOUS_LOGINS) {
			Map<string, usertracker> sessionUsers = LiveUsers.getSessionUsers(
				company.getCompanyId());

			List<usertracker> userTrackers = new ArrayList<usertracker>(
				sessionUsers.values());

			for (UserTracker userTracker : userTrackers) {
				if (userId != userTracker.getUserId()) {
					continue;
				}

				JSONObject jsonObject = JSONFactoryUtil.createJSONObject();

				ClusterNode clusterNode =
					ClusterExecutorUtil.getLocalClusterNode();

				if (clusterNode != null) {
					jsonObject.put(
						"clusterNodeId", clusterNode.getClusterNodeId());
				}

				jsonObject.put("command", "signOut");

				long companyId = CompanyLocalServiceUtil.getCompanyIdByUserId(
					userId);

				jsonObject.put("companyId", companyId);
				jsonObject.put("sessionId", userTracker.getSessionId());
				jsonObject.put("userId", userId);

				MessageBusUtil.sendMessage(
					DestinationNames.LIVE_USERS, jsonObject.toString());
			}
		}

		if (PropsValues.SESSION_ENABLE_PHISHING_PROTECTION) {
....
....
</usertracker></usertracker></string,>

Any errors in backhand ? And even I've not tried it personally just share the code which exist in current version.
Tried by debugging the code and check whether its executing properly.
