User id starting with numeric

[Ganesan R]

Hi,

Can someone tell me the implications if we create user id's starting with numeric ?

It is understood that useradd or SAM will not allow you to create it. But if we have modify the passwd file manually.

we have a requirement to create that kind of users..

Thanks in advance.

You can create such users in 11.31 - http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=NumericUserGroup

Short answer is you need to be on the Sept 08 release of 11iv3 to get this support. There are details in the release notes here:

http://docs.hp.com/en/5992-4174/ch10s10.html

And the package can be downloaded from here:

http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=NumericUserGroup

Prior to that it is *not* supported, so don't try it.

If the username is numeric first is searched as a UID, not a NAME.

See performance section here - http://docs.hp.com/en/5992-4174/ch10s10.html

1) "will it be any misbehaviour if the user id starting with numeric ?"

prior answers:

* Need to be at 11v3, Sept 2008 release to do this
* Prior to that it is *not* supported, so don't try it!
* If the username is numeric first is searched as a UID, not a NAME.
*See performance section here: ... which states"
"Performance

Without Numeric User Group Name feature, a numeric input was assumed as user/group ids, by a few commands. Hence, the id database was searched to find the corresponding entry.

However, with this feature, the user or group name database is first searched to find if it is a valid user or group name. If not, the user or group id database is searched.

This behavior is expected."

"Shall I go ahead and create user like this?"
State stated repeatedly...NO. Its not going to work, and will potentially cause problems.

Yikes, did you even take a minute to read the document Ivan cited? If you had, you would have had your answer. Look at the commands impacted by this change!
