openldap needs /lib/tls

[robert]

Hi,

I'm having problems getting openldap to work below is an line from:

 strace service ldap start

open("/lib/tls/libc.so.6", O_RDONLY)    = -1 ENOENT (No such file or directory)

Has anybody solved this one I would sure like to know.

We have a "Xen friendly" NPTL libc almost ready for release. For the
moment, you could try leaving the current tls library in place and use
the LD_ASSUME_KERNEL= trick to cause most binaries not to use it, execpt
openldap.

Are you sure this is causing the failure?  This seems pretty normal if
you have moved /lib/tls out of the way and not updated the ld cache
(by running ldconfig).  The next line in your strace file should show
that it falls back to /lib/libc.so.6 like this:
open("/lib/tls/libc.so.6", O_RDONLY)    = -1 ENOENT (No such file or directory) 
open("/lib/libc.so.6", O_RDONLY)        = 3  

It's possible that openldap doesn't work without /lib/tls, but the
error above is non-fatal and failure will occur later, if at all.  It
certainly starts up for me with /lib/tls moved out of the way and I
can do slapcat.

What distribution are you using?

FC3 OpenLDAP doesn't work with either bdb or ldbm. I had to compile from
source to use gdbm.

Some problem with futex, I think.

I use OpenLDAP for authentication (via PAM) and name lockup on a debian
sarge based xen box without problem. This is just client side, though.

Oh yes, I've seen that on a different system where some of the
backends wouldn't work because of bugs in the pthreads library.
If you don't want to recompile from source, it should work (with some
performance degradation) by moving /lib/tls back.
