    Thanks

    Looking at your screen shot, it seems the database instance itself hasn't been correctly created because you lack permissions to do so. Subsequently, all your connection attempts basically fail because the database does not exists. I'm no real expert in SAP MaxDB administration on Microsoft Windows, but I read about System Error 5 once in a while earlier, have a look at  [http://www.syseva.com/2009/05/operating-system-error-5-5access-is-denied/|http://www.syseva.com/2009/05/operating-system-error-5-5access-is-denied/]. Overally, I suspect you don't have the permissions you need to have (operating system/file system -wise) in order to create the files belonging to a MaxDB instance (and/or required by the server and tools, such as the dbmsrv ... err file mentioned in the screen). Maybe you should check your system permissions? Are you administrator or member of the appropriate groups [http://maxdb.sap.com/doc/7_7/0e/218650d996419d91f6b234766eadd3/content.htm|http://maxdb.sap.com/doc/7_7/0e/218650d996419d91f6b234766eadd3/content.htm]? As pointed out, I'm no MaxDB/Windows expert, but this seems likely to be a problem as far as your screenshot is concerned.

  • -24988 DBM -4008,Unknown user name/password combination

    Hello,
    I am not able to connect Whit database Manager Gui 7.6 with the standard user and password, (control,control e.g). The Database Manager Client show the follow error:
    -24988 DBM -4008,Unknown user name/password combination
    but from the dbhost with dbmcli, the logon is possibile (dbmcli -d LCX -u control,control).
    Any idea ?

    OS AIX 5.3
    OS client XP

    Hello ALF,
    1)
    Please check if you have the user data set in the config database file using dbm command
    on the database server < as you wrote, you have "SAPDB version:KERNEL 7.4.2 BUILD 030-122-117-803" >:
    dbmcli -d LCX -u control,control dbm_configget SAPDB12
    If the above command didn't return you the 'control' user, run:
    dbmcli -d LCX -u control,control dbm_configset SAPDB12 control
    && try to connect to the database in DBMGUi with control user again.
    2)
    If the 1) step didn't help, please try delete the entry for the database in DBMGUI &
    Add the database again.
    Update with the results of the recommended steps.
    Thank you and best regards, Natalia Khlopina

  • Recurring [-4008]: Unknown user name/password combination

    Hi,
    I am using MaxDB 7.6.00 BUILD 012-123-102-632 with JBoss through the JDBC Driver 7.6.0 on a Windows XP box.
    Sometimes, seldomly, after a reboot, I have the error :
    2008-05-28 14:52:40,093 WARN http://org.jboss.resource.connectionmanager.JBossManagedConnectionPool Throwable while attempting to get a new connection: null
    org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (com.sap.dbtech.jdbc.exceptions.DatabaseException: -4008: Unknown user name/password combination)
    When this happens, I can still connect to the databse using both the "Database Manager" or the java based "Db Visualizer" connecting as JBOSS/JBOSS. The "JBoss" user is registered as being of the type "dba".
    If I stop the sapdb windows service and my JBoss server windows service and restart them slowly and calmly. The problem disapears.
    I suspect that, sometimes, for some reason, my JBoss server tries to connect with the database when the latter is not "completely" ready. But by "completely" I don't really know what I mean.
    Did anyone experience that kind of problem ?
    Thank you

  • Can not connect to MaxDB 'Unknown user name/password combination' returned

    Hi,
         I try to make a connection from NWDS 7.2 to MaxDB. So i use the url as 'jdbc:sapdb://127.0.0.1:7210/CE1' to make a connection (by wizard of data source explorer in NWDS).
    I try to entry username and password as below :
    User : 'Administrator' , Pass : 'admin123'
    User : 'SAPJ2EDB' , Pass : 'admin123'
    User : 'superdba' , Pass : 'admin123'
    User : 'control' , Pass : 'admin123'
    So i always got
    com.sap.dbtech.jdbc.exceptions.jdbc40.SQLInvalidAuthorizationSpecException: [-4008]: Unknown user name/password combination
    returned
       I quite sure that 'admin123' is the password for MaxDB because when i try to uninstall the MaxDB it ask me to input password for 'superdba' and 'control'
    How should i do? I remember that when i installed the SAP CE7.2 i had entered just only one password.
    How can i reset the username and password or use default password?
    P.S i try to enter user and pass from this post MAXDB Server,Database,Username and pasword , but it still not work .

    Hi there,
    looks like you entered "DBADMIN" when you created the liveCache instance in DBMGUI as the DBM Operator.
    For SAP installations, this user is always named "CONTROL".
    So, drop the instance again, recreate it with "CONTROL" and re-do the recovery of the liveCache backup.
    regards,
    Lars

  • Auto-update: invalid user name / password

    Hello,
    I have changed out the CCO username and password for an IPS configured for auto-update but cannot get the IPS to correctly update its signature any longer.  I have verified that the CCO login is correct and that it can download a signature file directly using a web browser interface. However, every attempt to get the IPS to update automatically results in the following error:
    Auto Update Statistics
       lastDirectoryReadAttempt = 15:05:29 UTC Mon Sep 29 2014
        =   Read directory: https://72.163.4.161//cgi-bin/front.x/ida/locator/locator.pl

    (Note: I have the URL set to 'www.cisco.com')
    Thanks,

    FYI - just to close my own issue.
    The issue was resolved by using the cli to set the values and perform a one-time update. Once that was successful, all future signature updates have worked fine through the gui.

    Hi Ychinnari,
    I have tested on my local environment and can reproduce the issue, as
    Vaishu00547 mentioned that the issue can be caused by the Execution Account you have configured in the Reporting Services Configuration Manager is not correct, Please update the Username and Password and restart the reporting services.
    Please also find more details information about when to use the execution account, if possible,please also not specify this account:
    This account is used under special circumstances when other sources of credentials are not available:
    When the report server connects to a data source that does not require credentials. Examples of data sources that might not require credentials include XML documents and some client-side database applications.
    When the report server connects to another server to retrieve external image files or other resources that are referenced in a report.
    Execution Account (SSRS Native Mode)
    If you still have any problem, please feel free to ask.
    Regards

  • "Logon failure: unknown user name or bad password" even with correct Credentials

    I have networked PCs before many times successfully, so this is not my first time trying to network PCs in a home environment. Though I’m wondering if Windows 8.1 is part of the problem. 
    I would have thought that for sure, until one of the new laptops running W8.1 would not connect to any of the other three PCs/Laptops running W8.1. Yet these other three W8.1 PCs/Laptops CAN connect to this laptop. Then it gets a little more interesting:
    this same laptop that couldn’t connect to those three W8.1 PCs/Laptops, CAN connect to a Windows 7 desktop, and a XP Laptop, and those two can also connect back to it without issue. It’s almost like my network is divided in half, and only half can talk to
    each other. But then when I thought it couldn’t get any more interesting, I realized the first three W8.1 PCs/Laptops can talk to the others, it’s just that the others (W8.1 Laptop, W7 Desktop, XP Laptop) can’t talk back to them without getting the error,
    "Logon failure: unknown user name or bad password” even though the username and password are 100% correct.
    I don’t fully understand this error, because on the surface, it’s just WRONG! 
    My username and password are correct, but it appears something somewhere is interfering or hijacking the authentication process. Three of the computers (laptops) are brand new, just purchased last week and setup this week. The HostPC is also fairly new,
    just purchased last month.
    I am not using a HomeGroup, and have removed all computers that were part of a HomeGroup. I have enabled file sharing and network discovery and enabled “Use user accounts and passwords to connect to other computers” on all PCs.
    I have DSL and am using the wireless modem provided by my ISP which has router functionality built into it. It is a Sagemcom Model: F@ST 1704N.
    All computers are connected wirelessly. Time is correct on all PCs. I cannot use Group Policy, since they're all Standard or Home edition. DHCP is enabled and all computers are on the same subnet, using the 192.168.254.x range of ip addresses.
    The six computers are as follows: (I figured this may make is easier to visualize the layout)
    HostPC: HP Desktop W8.1           
    PC Name: DrsBlend
    U/N: DrsBlend  p/w: 123456 (not showing my real password)
    PC1: HP Laptop W8.1
    PC Name: DrsBlend-1
    U/N: DrsBlend    P/W: 123456
    PC2: HP Laptop W8.1
    PC Name: DrsBlend-2
    U/N: DrsBlend    P/W: 123456
    PC3: HP Laptop W8.1
    PC Name: DrsBlend-3
    U/N: DrsBlend    P/W: 123456
    PC4: HP Desktop W7 SP1
    PC Name: DrsBlend-4
    U/N: DrsBlend    P/W: 123456
    PC5: Dell Laptop XP SP3
    PC Name: DrsBlend-5
    U/N: DrsBlend    P/W: 123456
    Every PC stated above has the same user name and password and is logged-in with the username, DrsBlend and the password 123456. The "Logon failure: unknown user name or bad password” happens when trying to access HostPC, PC1, or PC2 from PC3, PC4, or
    PC5.
    The HostPC can see and connect to all the PCs, but only PC1 and PC2 can talk back or access the HostPC. 
    It’s like the HostPC and PC1, and PC2 are in their own little clique, and can talk back and forth to each other. Those three PCs can also talk to PC3, PC4, and PC5 as well, but PC3, PC4, and PC5 cannot talk back to them (HostPC, PC1, PC2).
    Profile corruption? I would have entertained that thought, but the fact the first three PCs can access and talk to one another kind of defeats that idea, and the fact the PCs were just recently setup.
    Firewall? Disabled, and disabled TrendMicro with no change. With them on/off, the first three PCs can still talk to each other and the rest of the PCs.
    Anyone have any additional suggestions?

    Hi，
    How did you connect to other PCs? Do you use RDP to connect to other PCs? If so, check the version of the RDP, as I know, some low version RDP can't connect to higher Windows like 8.1.
    And could you please tell us the detailed information about how the six PCs connect to the home network?
    Can PC1, PC2, PC3 ping back to host PC, PC1 and PC2?
    You can also run command " rundll32.exe keymgr.dll, KRShowKeyMgr " view the credentials stored in your PC,check whether this issue is related with some old credentials stored in your system.
