Re: [nssldap] Failed to bind to LDAP server - Can't contact LDAP server only on certain programs

[Bernhard Thalmayr <Bernhard.Thalmayr [at] Sun.COM>]

Hi Larry, I' ve seen this behaviour if the program calling nss_ldap is 
linked with a different ldap-library as nss_ldap has been linked with.

If the programm is running do a 'pmap <pid_of_process>' and  check if 2 
different ldap libraries have been loaded.

If you can not use LD_PRELOAD and you  can not link nss_ldap with the 
same ldap lib I feare you're out of luck.

I'm facing a similar issue with Solaris 10u5. The first call 'crashed' 
nscd and then the process is dynamically loading nss_ldap which has been 
linked to libldap.so.5 but the process calling 'getXbyY has been linked 
to libldap.so.5
