wso2 wso2-enterprise-integrator user-management wso2-esb

Unable to Login into WSO2 EI 6.5.0 after editing user-mgt.xml

I am trying to change admin credentials in WSO2 EI 6.5.0 by following WSO2 DOC.

By using WSO2 Management console, i can able to modify admin password as described here in the section called "Change password using the previous password" and can able to login with new password.

I have created new username/password(as "wso2admin" with admin role) in management console and successfully logging in.

I wanna set this new credentials as default admin credentials, So i edited user-mgt.xml file configuration as described below

 <Configuration>
        <AddAdmin>true</AddAdmin>
        <AdminRole>admin</AdminRole>
        <AdminUser>
            <UserName>wso2admin</UserName>
            <Password>wso2admin</Password>
        </AdminUser>
        <EveryOneRoleName>everyone</EveryOneRoleName> <!-- By default users in this role sees the registry root -->
        !-- Enable username claim retrieve from the UM_USER_NAME in JDBC datasources -->
        <OverrideUsernameClaimFromInternalUsername>true</OverrideUsernameClaimFromInternalUsername>
        <Property name="isCascadeDeleteEnabled">true</Property>
        <Property name="dataSource">jdbc/WSO2CarbonDB</Property>
    </Configuration>

after restarting server, i am getting below error and unable to get management console url

[2022-06-06 21:22:33,819] []  INFO - TaglibUriRule TLD skipped. URI: http://tiles.apache.org/tags-tiles is already defined

after getting thie ERROR, I tried to replace with default credentials(as "admin" rather than "wso2admin") in same user-mgt.xml file which also giving same kinda ERROR.

Note: Embedded H2 Database is in my local system(windows).

Here 2 clarification required.

How to recover from this failure, so that i can able to login to management console?
How to change default admin credentials (username/password)?

Solution

As @ycr mentioned, there is some class reference ERROR in user-mgt.xml config file.

How to recover from this failure, so that i can able to login to management console?

ERROR in config:

<UserStoreManager class="4">

Correction in Config:

<UserStoreManager class="org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager">

after made above change, management console url i got in log file and able to login.

How to change default admin credentials (username/password)?

I directly put newly created username, password in user-mgt.xml config like below.

<Configuration>
        <AddAdmin>true</AddAdmin>
        <AdminRole>admin</AdminRole>
        <AdminUser>
            <UserName>wso2admin</UserName>
            <Password>wso2admin</Password>
        </AdminUser>
        <EveryOneRoleName>everyone</EveryOneRoleName> <!-- By default users in this role sees the registry root -->
        !-- Enable username claim retrieve from the UM_USER_NAME in JDBC datasources -->
        <OverrideUsernameClaimFromInternalUsername>true</OverrideUsernameClaimFromInternalUsername>
        <Property name="isCascadeDeleteEnabled">true</Property>
        <Property name="dataSource">jdbc/WSO2CarbonDB</Property>
    </Configuration>

PS:

Unable to delete Old Super admin since that Delete Operation is disabled by default. PFB for reference.

If you see above image, you could see that For newly created User (admin as role), All Operations like Change password, Assign/View Roles, Delete, User Profile are Disabled by default. Don't know why it happens.
