why we can't create username

372 0 1 0

【Problem Description】

1. We are not able to create the user credential under AAA. We are getting Error message of "Wrong parameter found at ^ position".

2. We also noticed that it showing ~ before the hostname of SW which might have some alarm or significance.

【Problem Analysis】

1. As we checked, the username only has 4 characters, for our security rule, the name should be at least 6 characters.

Parameter

Description

Value

user-name

Specifies the username.

The value is a character string in format user name+domain name delimiter+domain name. For example, in admin@huawei.com, @ is the domain name delimiter. The user name and domain name are case-insensitive, and cannot contain spaces and the following characters: / \ : * ? " < > | @ ' %. When security policy is enabled for local account, the value of user-name is a string of 6-253 characters; when security policy is disabled for local account, the value of user-name is a string of 1-253 characters. If no delimiter is specified, the system considers the entire character string as user name and the user belongs to the default domain.

NOTE:

After the security policy is disabled for local account, the * symbol can be used as a wildcard to match created user names and change passwords for the users in a batch.

2. When we disable security-enhance, the username can be configured as 1-253 characters.

<HUAWEI> system-view

[~HUAWEI] aaa

[~HUAWEI-aaa] undo local-user policy security-enhance

3. The character “~” means you are in configuration mode. The character “*” means you need to commit the configuration otherwise the new configuration will not take effect.

【Root Cause】

For security rule, the username should be at least 6 characters.

【Solution Description】

Run command “undo local-user policy security-enhance” to disable security-enhance, then the username can use 1-253 characters.
