USERDB: Unable to read from /var/adm/userdb/44. Run userdbck
Hi all,
Just installed HPUX v11.31 U7 on a rx2800.
About 5 times a day, I notice this error in the syslog:
"USERDB: Unable to read from /var/adm/userdb/44. Run userdbck"
When I run the userdbck, no problem is reported.
I have not been able to reproduce the problem manually by logging in, out, changing pwd, start stop applications...
The error messages appears during the day when users are logged on, nothing found during i.e. the weekend. My conclusion is that this is triggered by user activities somehow.
As I understand is this related to the settings in /etc/default/security and /etc/security.dsc,but no changes are made there.
Anyone who knows if it's possible to check more details about the problem, i.e. finding out what's trigger the error or know what 44 in the userdb is referring to?
Any answer is appreciated.

Re: USERDB: Unable to read from /var/adm/userdb/44. Run userdbck
Is it always file /var/adm/userdb/44 ??
What user is that? ( strings /var/adm/userdb/44 )
There are some notes in the internal knowledge base to indicate this error can be seen when there are authentication issues for example when using LDAP/Kerberos - are you just using /etc/passwd for authentication? Or something else?

Re: USERDB: Unable to read from /var/adm/userdb/44. Run userdbck
I have a few boxes where that deprecated behavior is in use, and we get those userdb warnings anytime someone logs into the jailed account. Using ChrootDirectory instead in sshd_config is the way to fix it in that case.

Re: USERS: Unable to read from /var/adm/userdb/44. Run userdbck
When checking the content of /var/adm/userdb/44 I've got following output:
# strings /var/adm/userdb/44
bardlar0
login_time=0x4f1d14bd
login_origin=optosoem
auth_ftime=0x4f1d14b9
auth_forigin=optosoem
:root
login_time=0x4f210869
login_origin=optosoem
auth_ftime=0x4f158d2b
auth_forigin=localhost
It seems somehow be related to user bardlar0 and also root is mentioned.
I'm not sure what conclusions that can be drawn from this.

Re: USERDB: Unable to read from /var/adm/userdb/44. Run userdbck
Hi,
The SMSE log files used in /var/adm/userdb range from 00-ff i.e in hexadecimal and the 44 corresponds to the user bardlar0. So I suggest that you investigate this user account as far as the SMSE security settings are concerned. It is clearly this account that is causing the problem. How about posting a userdbget on this account?
Regards
Ismail Azad

Re: USERDB: Unable to read from /var/adm/userdb/44. Run userdbck
Hi Ismail,
Thanks for your advice. I have investigated on the user bardlar0, but can not find anything that differ from the other users. I have tried to re-create the user but the problem remains.
I have also tried your advice to run userdbget on this user, but the command does not give any output at all. The fact is that userdbget does not give an output for any user or not even for userdbget -a
Following syntax has been used:
#userdbget -u bardlar0
and
#userdbget -a
No output at all just a new prompt.
