[Samba] Errors on migration from 3.0.4 to 3.0.24 with LDAP

Tue Apr 15 22:35:31 GMT 2008

Hi all,

I am encountering some error messages on the first launch of samba
3.0.24 using data stored in an LDAP directory by previous version 3.0.4.

These error messages occur only once on the first launch of the new
version of samba, never again. I would like to know what possible
consequences they have.

Detailed output is at the end of this message, here is a brief
description of both of the error messages:

1) "ERROR: string overflow by <n> in safe_strcat [-...]"
These messages have <n> varying from 2 to 11, and the string enclosed in
brackets ([]) is always "-" followed by some numbers (part of an SID?).
<n> also always corresponds to the length of the string in brackets.

 From reading the safe_strcat function in the code, this means the string
displayed is dropped, and not concatenated to another string. I am
unclear as to why, and what the consequences are.

After a series of them, the following lines are displayed:
> pdb_init_ldapsam: Resetting SID for domain ABC.DOM based on pdb_ldap results S-206-547431424-7-2396148-7-2149158415-3218881064-1556950-2170952608-2149158415-7-2149460952-2170952584-3218881200-3218881080-2148326621-2149158415-1025-83886080-21-832462299-1939947750-1103500926-0-0-0-0-0-0-0-0-0-0-0-1190148608-2149460952-2170949008-217 -> S-1-5-21-832462299-1939947750-1103500926
> New global sam SID: S-1-5-21-832462299-1939947750-1103500926

2) "account_policy_get: tdb_fetch_uint32 failed for field <n> (...),
returning 0"
These messages have <n> ranging from 1 to 10 (see full output below).

I read the following post stating these are unimportant, one-time only
messages. I assume this is still the case?
http://lists.samba.org/archive/samba/2005-September/110395.html

I am most keen for any pointers or ideas anyone here can provide as to 
the consequences of these messages. Thank you in advance.

Jonathan Clarke
