RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Steffen Froemer 2018-03-22 17:20:30 UTC
Description of problem:
Using nslcd for debugging LDAP authentication, errormessages are stripped at 200 characters

Version-Release number of selected component (if applicable):
nss-pam-ldapd-0.8.13-8.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.
2.
3.

Actual results:
nslcd: [8b4567] <passwd="user"> ldap_start_tls_s() failed (uri=ldaps://server1.example.com:636/): Server is unavailable: The TLS connection security provider cannot be enabled on this client connection because it is already usi...
nslcd: [8b4567] <passwd="user"> failed to bind to LDAP server ldaps://server1.example.com:636/: Server is unavailable: The TLS connection security provider cannot be enabled on this client connection because it is already using...



Expected results:
The error message should be printed completely

Additional info:
Checking the Source, it seems it's hardcoded value.

https://github.com/arthurdejong/nss-pam-ldapd/blob/master/nslcd/log.c

/* log the given message using the configured logging method */
void log_log(int pri, const char *format, ...)
{
  int res;
  struct log_cfg *lst;
  char buffer[200];                                  ----> this limits to 200 char
  va_list ap;
#ifndef TLS
  char *sessionid, *requestid;
  pthread_once(&tls_init_once, tls_init_keys);
  sessionid = pthread_getspecific(sessionid_key);
  requestid = pthread_getspecific(requestid_key);
#endif /* no TLS */
  /* make the message */
  va_start(ap, format);
res = vsnprintf(buffer, sizeof(buffer), format, ap);             ---> here it truncates to 200
