problem with account modification in latest cpanel release

[LAZer]

hi , i have faced a major problem with account modification function in latest release of cpanel/whm - problem happens when i want to rename username of an account.
( hopefully i had the fullbackup of my user accounts )

i use RELEASE Builds (Automatic) which is now WHM 11.28.83

Modify an Account
Account Not Modified
Error.. update of Apache conf failed. Please check the Apache conf.
Account modification aborted, there was a problem changing the user name.

i have created apache.conf with
/scripts/ensure_vhost_includes --all-users
/scripts/rebuildhttpdconf

and they returned a httpd.conf build correctly. so i dont think the problem being from httpd.conf

i have checked httpd.conf after the error when it failed to rename user1 to user2

root@server2 [/home]# /usr/local/apache/bin/httpd -t
Warning: DocumentRoot [/home/user1/public_html] does not exist
httpd: bad user name user1



for example i have , user1 , in list of accounts , and i want to change the user name to user2 , and there are total of X accounts in user list.

when i use account modify script there is an error at the end of modification which causes big problem for apache.
script changes the dir name /home/user1 -->/home/user2,
also owner and group of the files inside it changes correctly,
and also it changes the name of the files in
/var/cpanel/userdata and /var/cpanel/users
and also in /etc/passwd

but the problem is with the following changes :
db name donot change , in /var/lib/mysql , user_db donot change to user1_db
also in /etc/passwd- , the line of user donot change.

/etc/shadow and /etc/group changed sometimes.

then if you do a httpd config rebuild or restart it gives the following error :
invalid group user2

and it stops creating httpd.conf and apache fails to restart

/scripts/rebuildhttpdconf
/scripts/ensure_vhost_includes --all-users
fail to create new httpd.conf

-----
then in list of accounts there will be no name from those users ! no user1 or no user2
but the count of accounts donot change and still shows X accounts and not ( x -1 )
in the terminate accounts they are available but it cannot terminate that

Terminate an Account

Account Removal Status: failed (System user [user1] does not exist!)System user [user1] does not exist!

---------------
solution to bring up apache again :

remove the lines of /etc/passwd , /etc/passwd- , remove files of those users from
/var/cpanel/users , and /var/cpanel/userdata
remove anyother trace of the 2 users:
egrep username /etc/passwd /etc/shadow /etc/group

( more info for solution at :
http://forums.cpanel.net/f5/account-...st-153637.html
whm - Why can't I change cPanel user account name in Web Host Manager? - Server Fault
)

delete mysql user :
# mysql
# drop user user@localhost;

drop dns records from whm --> delete a dns zone

also delete any other trace of files in /var or /etc or /usr
find /var -name 'user*' -exec rm {} \;
find /usr -name 'user*' -exec rm {} \;
find /etc -name 'user*' -exec rm {} \;

then you can create a test user with the same name user1 and user2 and delete them with account terminate .
then rebuild httpd.conf and restart apache.
then restore the fullbackup of your user1 account.


now someone please test to see if this is my problem so that i open a support ticket or is it a bug in new release ? thanks in advanced

Hello LAZer,

I just tested 11.28.83-RELEASE_51164 machine for this issue by first changing the username for an existing account in WHM > Modify an Account area. The username did change successfully without any errors.

Next, I created a new account in WHM > Create a New Account area, and then changed the username for that account in WHM > Modify an Account area. Again, that username did change without any errors.

As such, I cannot reproduce this issue occurring on 11.28.83 on our test machine. Please do open up a ticket in WHM > Support Center > Contact cPanel or using the link that I have in my signature.

Thanks!

thanks for testing. so this is a problem with my apache httpd.conf
the strange thing is that i could use this function already without any errors.

can you update httpd.conf with these 2 commands before modifying the account ?

/scripts/rebuildhttpdconf
/scripts/ensure_vhost_includes --all-users

i think there must be a problem with those included user .conf files then. i`ll test again and read config files and let you know again. thanks

You can goahead and try to first get fresh copy of your cpanel by doing the /scripts/upcp --force and then try the things again
and also please make sure that Drive and the configuration files like httpd.conf and the /etc/password /etc/shadow are not attributed

i have force upgraded the cpanel but no changes.
the strange thing is that when i create a new account , and use modify account script on that , the script works fine. but when i use modify account on my existing users it fails with the same error.
i dont know what to do , should i open a support ticket or simply forget it ? because i cant try this on my existing users anymore , yesterday i had about 1 hour downtime till ifound the solution

i encountered such error with an account whose mysql was 5+gb , modification script kept on running for almost 1 hour at last browser stopped.

[LAZer]

yes the account which i faced the problem with is a hightraffic account. but now i face the same problem on small accounts even a 50 mb account ! i have created a new account and i`m trying to import the full backup to it.

i dont know if renaming the file name of a backup can change the name of the restored backup or not?
for example i have backup of user1.tar.gz and i want to import it as user2 , what should i do ?

now i have created user2 from whm , and i`m trying to import that fullbackup some how to it . i dont know if it will work or not.

[bhanuprasad1981]

my scene was user name was same but domains different , so i created new account and manually copied files/mysql i had no choice
