Can't login with several usernames

Hi,

After installing v7.8.3 and creating new users some of the users just can’t login with “Wrong username / password” error and “Session expired” flash at the top of the screen. They were using credentials from “New account information” email, password was generated by the system. I’ve cleaned browser cache between login attempts and tried to login from 2 computers with no luck, but after changing usernames of those users problem magically disappeared. I’m completely confused about the issue, because as far as I know, there’s no requirements for username’s length or content.

Not sure if this could help, but problem usernames were vs and mmp.

Here’s the suitecrm.log entries for this:

Tue Jun 20 10:09:33 2017 [1427][-none-][FATAL] SECURITY: User authentication for vs failed
Tue Jun 20 10:09:33 2017 [1427][-none-][FATAL] FAILED LOGIN:attempts[1] - vs
Tue Jun 20 10:10:05 2017 [3100][1][FATAL] Exception in Controller: Error retrieving record. This record may be deleted or you may not be authorized to view it.
Tue Jun 20 10:13:34 2017 [3101][aafb0782-d6ab-0a25-daf6-59479c524a35][FATAL] Exception in Controller: Error retrieving record. This record may be deleted or you may not be authorized to view it.

Can you write down an exact list of “steps to reproduce” the problem?

The problem could be during user creation, not during login… any errors in log at the moment of creation?

I’m having a similar problem, but my installation was working fine until today, when suddenly some of my users can’t login, but I can log in as the Admin user just fine.

These are users who have been using it fine for a long time, but are just having problems today.

All the log says is

Thu Jan 18 11:03:10 2018 [29729][-none-][FATAL] FAILED LOGIN:attempts[1] - Emily

I found the solution here.

I had to disable the SuitePImproved theme and then get everyone to clear their browser cache (Ctrl+F5)

For me the problem was solved by editing login.tpl

The password field had the wrong name.

<input type="password" class="form-control" placeholder="{sugar_translate module="Users" label="LBL_PASSWORD"}" tabindex="2" id="user_password" name="user_password" value='{$LOGIN_PASSWORD}'/>

Change to:

<input type="password" class="form-control" placeholder="{sugar_translate module="Users" label="LBL_PASSWORD"}" tabindex="2" id="user_password" name="username_password" value='{$LOGIN_PASSWORD}'/>
